Broken Bonds
============
Typically, bond interactions persist for the duration of a simulation in
LAMMPS. However, there are some exceptions that allow for bonds to
break, including the :doc:`quartic bond style <bond_quartic>` and the
bond styles in the :doc:`BPM package <Howto_bpm>` which contains the
:doc:`bpm/spring <bond_bpm_spring>` and :doc:`bpm/rotational
<bond_bpm_rotational>` bond styles. In these cases, a bond can be broken
if it is stretched beyond a user-defined threshold. LAMMPS accomplishes
this by setting the bond type to 0, such that the bond force is no
longer computed.
Typically, molecular bond interactions persist for the duration of a
simulation in LAMMPS. However, some commands break bonds dynamically,
including the following:
Users are normally able to weight the contribution of pair forces to atoms
that are bonded using the :doc:`special_bonds command <special_bonds>`.
When bonds break, this is not always the case. For the quartic bond style,
pair forces are always turned off between bonded particles. LAMMPS does
this via a computational sleight-of-hand. It subtracts the pairwise
interaction as part of the bond computation. When the bond breaks, the
subtraction stops. For this to work, the pairwise interaction must always
be computed by the :doc:`pair_style <pair_style>` command, whether the bond
is broken or not. This means that :doc:`special_bonds <special_bonds>` must
be set to 1,1,1. After the bond breaks, the pairwise interaction between the
two atoms is turned on, since they are no longer bonded.
* :doc:`bond_style quartic <bond_quartic>`
* :doc:`fix bond/break <fix_bond_break>`
* :doc:`fix bond/react <fix_bond_react>`
* :doc:`BPM package <Howto_bpm>` bond styles
In the BPM package, one can either turn off all pair interactions between
bonded particles or leave them on, overlaying pair forces on top of bond
forces. To remove pair forces, the special bond list is dynamically
updated. More details can be found on the :doc:`Howto BPM <Howto_bpm>`
page.
A bond can break if it is stretched beyond a user-defined threshold or
more generally if other criteria are met.
Bonds can also be broken by fixes which change bond topology, including
:doc:`fix bond/break <fix_bond_break>` and
:doc:`fix bond/react <fix_bond_react>`. These fixes will automatically
trigger a rebuild of the neighbor list and update special bond data structures
when bonds are broken.
For the quartic bond style, when a bond is broken its bond type is set
to 0 to effectively break it and pairwise forces between the two atoms
in the broken bond are "turned on". Angles, dihedrals, etc cannot be
defined for a system when :doc:`bond_style quartic <bond_quartic>` is
used.
Note that when bonds are dumped to a file via the :doc:`dump local <dump>` command, bonds with type 0 are not included. The
:doc:`delete_bonds <delete_bonds>` command can also be used to query the
status of broken bonds or permanently delete them, e.g.:
Similarly, bond styles in the BPM package are also incompatible with
angles, dihedrals, etc. and when a bond breaks its type is set to zero.
However, in the BPM package one can either turn off all pair interactions
between bonded particles or leave them on, overlaying pair forces on
top of bond forces. To remove pair forces, the special bond list is
dynamically updated. More details can be found on the :doc:`Howto BPM
<Howto_bpm>` page.
The :doc:`fix bond/break <fix_bond_break>` and :doc:`fix bond/react
<fix_bond_react>` commands allow breaking of bonds within a molecular
topology with may also define angles, dihedrals, etc. These commands
update internal topology data structures to remove broken bonds, as
well as the appropriate angle, dihederal, etc interactions which
include the bond. They also trigger a rebuild of the neighbor list
when this occurs, to turn on the appropriate pairwise forces.
Note that when bonds are dumped to a file via the :doc:`dump local
<dump>` command, bonds with type 0 are not included.
The :doc:`delete_bonds <delete_bonds>` command can be used to query
the status of broken bonds with type = 0 or permanently delete them,
e.g.:
.. code-block:: LAMMPS
delete_bonds all stats
delete_bonds all bond 0 remove
The compute :doc:`nbond/atom <compute_nbond_atom>` can also be used
to tally the current number of bonds per atom, excluding broken bonds.
The compute :doc:`count/type <compute_count_type>` command tallies the
current number of bonds (or angles, etc) for each bond (angle, etc)
type. It also tallies broken bonds with type = 0.
The compute :doc:`nbond/atom <compute_nbond_atom>` command tallies the
current number of bonds each atom is part of, excluding broken bonds
with type = 0.

.. index:: compute count/type
compute count/type command
====================
Syntax
""""""
.. code-block:: LAMMPS
compute ID group-ID count/type mode
* ID, group-ID are documented in :doc:`compute <compute>` command
* count/type = style name of this compute command
* mode = {atom} or {bond} or {angle} or {dihedral} or {improper}
Examples
""""""""
.. code-block:: LAMMPS
compute 1 all count/type atom
compute 1 flowmols count/type bond
Description
"""""""""""
.. versionadded:: TBD
Define a computation that counts the current number of atoms for each
atom type. Or the number of bonds (angles, dihedrals, impropers) for
each bond (angle, dihedral, improper) type.
The former can be useful if atoms are added to or deleted from the
system in random ways, e.g. via the :doc:`fix deposit <fix_deposit>`,
:doc:`fix pour <fix_pour>`, or :doc:`fix evaporate <fix_evaporate>`
commands. The latter can be useful in reactive simulations where
molecular bonds are broken or created, as well as angles, dihedrals,
impropers.
Note that for this command, bonds (angles, etc) are the topological
kind enumerated in a data file, initially read by the :doc:`read_data
<read_data>` command or defined by the :doc:`molecule <molecule>`
command. They do not refer to implicit bonds defined on-the-fly by
bond-order or reactive pair styles based on the current conformation
of small clusters of atoms.
These commands can turn off topological bonds (angles, etc) by setting
their bond (angle, etc) types to negative values. This command
includes the turned-off bonds (angles, etc) in the count for each
type:
* :doc:`fix shake <fix_shake>`
* :doc:`delete_bonds <delete_bonds>`
These commands can create and/or break topological bonds (angles,
etc). In the case of breaking, they remove the bond (angle, etc) from
the system, so that they no longer exist (:doc:`bond_style quartic
<bond_quartic>` and :doc:`BPM bond styles <Howto_bpm>` are exceptions,
see the discussion below). Thus they are not included in the counts
for each type:
* :doc:`delete_bonds remove <delete_bonds>`
* :doc:`bond_style quartic <bond_quartic>`
* :doc:`fix bond/react <fix_bond_react>`
* :doc:`fix bond/create <fix_bond_create>`
* :doc:`fix bond/break <fix_bond_break>`
* :doc:`BPM package <Howto_bpm>` bond styles
----------
If the {mode} setting is {atom} then the count of atoms for each atom
type is tallied. Only atoms in the specified group are counted.
If the {mode} setting is {bond} then the count of bonds for each bond
type is tallied. Only bonds with both atoms in the specified group
are counted.
For {mode} = {bond}, broken bonds with a bond type of zero are also
counted. The :doc:`bond_style quartic <bond_quartic>` and :doc:`BPM
bond styles <Howto_bpm>` break bonds by doing this. See the :doc:`
Howto broken bonds <Howto_broken_bonds>` doc page for more details.
Note that the group setting is ignored for broken bonds; all broken
bonds in the system are counted.
If the {mode} setting is {angle} then the count of angles for each
angle type is tallied. Only angles with all 3 atoms in the specified
group are counted.
If the {mode} setting is {dihedral} then the count of dihedrals for
each dihedral type is tallied. Only dihedrals with all 4 atoms in the
specified group are counted.
If the {mode} setting is {improper} then the count of impropers for
each improper type is tallied. Only impropers with all 4 atoms in the
specified group are counted.
----------
Output info
"""""""""""
This compute calculates a global vector of counts. If the mode is
{atom} or {bond} or {angle} or {dihedral} or {improper}, then the
vector length is the number of atom types or bond types or angle types
or dihedral types or improper types, respectively.
If the mode is {bond} this compute also calculates a global scalar
which is the number of broken bonds with type = 0, as explained above.
These values can be used by any command that uses global scalar or
vector values from a compute as input. See the :doc:`Howto output
<Howto_output>` page for an overview of LAMMPS output options.
The scalar and vector values calculated by this compute are "extensive".

analyse the phonon related information.
#-------------------------------------------------------------------------------
1. Dependencies
The clapack library is needed to solve the eigen problems,
which could be downloaded from:
http://www.netlib.org/clapack/
The ZHEEVD LAPACK function is needed to solve the eigen problems.
A C++ compilable version based on CLAPACK is included in the linalg folder
and will be automatically built.
The tricubic library is also needed to do tricubic interpolations,
which could now be obtained from:
https://github.com/nbigaouette/libtricubic/
The tricubic library is also needed to do tricubic interpolations.
A copy is included and will be automatically built.
The spglib is optionally needed, enabling one to evaluate the
phonon density of states or vibrational thermal properties
using only the irreducible q-points in the first Brillouin zone,
as well as to evaluate the phonon dispersion curvers with the
automatic mode. Currently, the 1.8.3 version of spglib is used.
It can be obtained from:
http://spglib.sourceforge.net/
automatic mode. Currently, version 1.11.2.1 of spglib is used.
It is automatically downloaded and compiled unless the -DUSE_SPGLIB=off
variable is set during CMake configuration.
FFTW 3 might also be needed if you would like to interface with
phonopy: necessary input files for phonopy will be prepared so
that you can make use of the functions provided by phonopy.
FFTW 3 can be downloaded from:
http://www.fftw.org
It is autodetected and used if available.
FFTW 3 can be downloaded from: http://www.fftw.org
2. Compilation
To compile the code, one needs therefore to install the above
libraries and set the paths correctly in the Makefile.
Once this is done, by typing
make
will yield the executable "phana".
To compile the code, one needs to have CMake version 3.16
or later installed.
The CMake configuration is done with:
cmake -S . -B build
And compilation then performed with:
cmake --build build
The phana (or phana.exe) executable is then available in
the "build" folder
3. Unit system
The units of the output frequencies by this code is THz for
@ -46,6 +50,18 @@
5. Bug report
If any bug found, please drop a line to: konglt(at)sjtu.edu.cn
6. Precompiled executable
The "precompiled" folder contains a precompiled and statically
linked Linux executable for x86_64 CPUs. It should work on *any*
Linux machine with using the x86_64 architecture. It includes
spglib support but not fftw3.
7. Portability
Build and use of phana has been successfully tested on:
- Fedora Linux 38 using GCC, Clang, and MinGW Linux2Windows cross-compiler
- macOS 12 (Monterey) using Xcode
- Windows 11 using Visual Studio 2022 with MSVC and Clang

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.

# libtricubic
This folder contains a slightly refactored version of version 1.0 of
the _libtricubic_ library, developed by François Lekien in 2004.
The following paper explaining the method was published in 2005:
> Lekien, F., & Marsden, J. (2005). _Tricubic interpolation in three
> dimensions._ International Journal for Numerical Methods in Engineering,
> 63(3), 455–471. doi:10.1002/nme.1296
Some additional notes and the full matrix can be found in the technical notes:
> Lekien, F., Coulliette, C., & Marsden, J. (2004). _Tricubic Engine - Technical
> Notes and Full Matrix.
The main article refers to the author's website
(http://gyre.cds.caltech.edu/pub/software/tricubic/) to download the code and
documentation. Unfortunately, this website no longer exists. Even the
archive.org snapshot is useless; [A single snapshot from December 3rd 2009 is
available](https://web.archive.org/web/20091203115835/http://gyre.cds.caltech.edu/pub/software/tricubic)
which seems like an FTP listing. No files are accessible.
The source code was obtained from https://github.com/nbigaouette/libtricubic/
Only the sources for the library were retained. No functional changes were
made, but some common programming conventions were applied, source files
merged, and build support for CMake added.
