ENH: add Test-EigenMatrix application
The new iterative eigen decomposition functionality is
derived from:
Passalacqua et al.'s OpenQBMM (openqbmm.org/),
which is mostly derived from JAMA (math.nist.gov/javanumerics/jama/).
- bundled of boolean values as a vector of 3 components with
element access using x(), y() and z() member functions.
It also has some methods similar to bitSet.
- Not derived from Vector or VectorSpace since it does not share very
many vector-like characteristics.
- support construct from initializer_list, which can help simplify
code with constant coefficients.
- add default constructor for polynomialFunction and Istream reading
to support resizable lists of polynomialFunction.
A default constructed polynomialFunction is simply equivalent to
a constant zero.
- no special IO handling for Polynomial required,
it is the same as VectorSpace anyhow.
- previously introduced `getOrDefault` as a dictionary _get_ method,
now complete the transition and use it everywhere instead of
`lookupOrDefault`. This avoids mixed usage of the two methods that
are identical in behaviour, makes for shorter names, and promotes
the distinction between "lookup" access (ie, return a token stream,
locate and return an entry) and "get" access (ie, the above with
conversion to concrete types such as scalar, label etc).
- Favour use of argList methods that are more similar to dictionary
method names with the aim of reducing the cognitive load.
* Silently deprecate two-parameter get() method in favour of the
more familiar getOrDefault.
* Silently deprecate opt() method in favour of get()
These may be verbosely deprecated in future versions.
- similar to the behaviour of std::ignore and consistent with the
no input / no output nature of nullObject. Similarly accept a
const reference for its Istream operator.
- make most nullObject methods constexpr
- mostly wraps std::chrono so can inline much of it, which is potentially
helpful when used for inner timings.
- add elapsedTime() method for direct cast to double and for
naming similarity with wall-clock method.
Potential breaking change (minor):
- clockValue construct with a bool parameter is now simply tagged
dispatch (value is ignored) and always queries the current clock
value. This avoids needless branching.
Since this constructor form has primarily been used internally (eg,
clockTime), breakages in user code are not expected.
- have printBuildInfo output to std::ostream
- removed extraneous include "stdFoam.H"
ENH: revert to pre-processor defines for hard-coded paths (#1712)
- redundant information, but more robust at run-time without relying
on initialization order
- less frequently used, but the information was previously inaccessible
under etcFiles.C.
Now exposed within the foamVersion namespace and defined under
<global.Cver> to improve configuration possibilities.
- simplified templating, which cleans up code and does not appear to
break any normal user coding.
ENH: unique_ptr instead of homegrown demand-driven handling.
- takes a search string and a replacement character.
The replacement character can also be a nul char ('\0'), which
simply removes the characters.
Possible uses:
* Replace reserved characters
str.replaceAny("<>:", '_');
* Remove shell meta-characters or reserved filesystem characters
str.replaceAny("*?<>{}[]:", '\0');
- adjustments to internal handling to improve run-time addition of
other formats (eg, with additional user library)
For example, to write a binary STL with a '.stl' extension:
$ surfaceMeshConvert input.obj -write-format stlb output.stl
Or in a sampler,
to specify the input type without ambiguity:
surf
{
type meshedSurface;
surface sampling.inp;
fileType starcd;
scale 0.001;
...
}
STYLE: regularize naming for input/output scaling
* -read-scale (compat: -scaleIn)
* -write-scale (compat: -scaleOut)
CONFIG: change edge/surface selection name for STARCD format
- now select as "starcd" instead of "inp" to avoid naming ambiguity
with abaqus
- face_type, point_type (similar to STL value_type, etc).
The naming avoids potential confusion with template parameters.
- rename private typedef from ParentType to MeshReference for more
consistency with polySurface etc.
- previously used a Pstream::exit() invoked from the argList
destructor to handle all MPI shutdown, but this has the unfortunate
side-effect of using a fixed return value for the program exit.
Instead use the Pstream::shutdown() method in the destructor and allow
the normal program exit codes as usual. This means that the
following code now works as expected.
```
argList args(...);
if (...)
{
InfoErr<< "some error\n";
return 1;
}
```
Style changes:
- use std algorithm for some stringOps internals
- pass SubStrings iterators by const reference
ENH: special nullptr handling for ISstream getLine
- pass through to istream::ignore to support read and discard
* Support default values for format/compress enum lookups.
- Avoids situations where the preferred default format is not ASCII.
For example, with dictionary input:
format binar;
The typing mistake would previously have caused formatEnum to
default to ASCII. We can now properly control its behaviour.
IOstream::formatEnum
(
dict.get<word>("format"), IOstream::BINARY
);
Allowing us to switch ascii/binary, using BINARY by default even in
the case of spelling mistakes. The mistakes are flagged, but the
return value can be non-ASCII.
* The format/compression lookup behave as pass-through if the lookup
string is empty.
- Allows the following to work without complaint
IOstream::formatEnum
(
dict.getOrDefault("format", word::null), IOstream::BINARY
);
- Or use constructor-like failsafe method
IOstream::formatEnum("format", dict, IOstream::BINARY);
- Apply the same behaviour with setting stream format/compression
from a word.
is.format("binar");
will emit a warning, but leave the stream format UNCHANGED
* Rationalize versionNumber construction
- constexpr constructors where possible.
Default construct is the "currentVersion"
- Construct from token to shift the burden to versionNumber.
Support token as argument to version().
Now:
is.version(headerDict.get<token>("version"));
or failsafe constructor method
is.version
(
IOstreamOption::versionNumber("version", headerDict)
);
Before (controlled input):
is.version
(
IOstreamOption::versionNumber
(
headerDict.get<float>("version")
)
);
Old, uncontrolled input - has been removed:
is.version(headerDict.lookup("version"));
* improve consistency, default behaviour for IOstreamOption construct
- constexpr constructors where possible
- add copy construct with change of format.
- construct IOstreamOption from streamFormat is now non-explicit.
This is a commonly expected result with no ill-effects
- renamed 'core/' -> 'base/' to avoid gitignore masking when re-adding
files
- rename 'nas/' to 'nastran/' for more clarity
- relocated OBJstream from surfMesh to fileFormats
STYLE: remove unused parseNASCoord. Was deprecated 2017-09
- `tensor` and `tensor2D` returns complex eigenvalues/vectors
- `symmTensor` and `symmTensor2D` returns real eigenvalues/vectors
- adds new test routines for eigendecompositions
- improves numerical stability by:
- using new robust algorithms,
- reordering the conditional branches in root-type selection
- ensures each Tensor-container operates for the following base types:
- floatScalar
- doubleScalar
- complex
- adds/improves test applications for each container and base type:
- constructors
- member functions
- global functions
- global operators
- misc:
- silently removes `invariantIII()` for `tensor2D` and `symmTensor2D`
since the 3rd invariant does not exist for 2x2 matrices
- fixes `invariantII()` algorithm for `tensor2D` and `symmTensor2D`
- adds `Cmpt` multiplication to `Vector2D` and `Vector`
- adds missing access funcs for symmetric containers
- improves func/header documentations
- provides an indirect access to a sub-section of a list that is
somewhat less efficient than a Foam::SubList, but supports the
following:
* adjustment of its addressing range after construction
* recovery of the original, underlying list at any time
This can be more convenient for some coding cases.
For example,
template<class Addr>
void renumberFaces(IndirectListBase<face, Addr>& faces, ...);
which can be called for
* Specific faces:
UIndirectList<face>(mesh.faces(), facesToChange)
* A sub-range of faces:
IndirectSubList<face>(mesh.faces(), pp.range())
* All faces:
IndirectSubList<face>(mesh.faces())
CONFIG: added IndirectListsFwd.H with some common forwarding
- now use debug 2 for scanner and debug 4 for parser.
Provided better feedback about what is being parsed (debug mode)
- relocate debug application to applications/tools/foamExprParserInfo
- follows the principle of least surprise if the expansion behaviour
for #eval and expressions (eg, exprFixedValue) are the same. This
is possible now that we harness the regular stringOps::expand()
within exprString::expand()
- reuse more of stringOps expansions to reduce code and improve the
syntax flexiblity.
We can now embed "pre-calculated" values into an expression.
For example,
angle 35;
valueExpr "vector(${{cos(degToRad($angle))}}, 2, 3)";
and the ${{..}} will be evaluated with the regular string evaluation
and used to build the entire expression for boundary condition
evaluation.
Could also use for fairly wild indirect referencing:
axis1 (1 0 0);
axis2 (0 1 0);
axis3 (0 0 1);
index 100;
expr "$[(vector) axis${{ ($index % 3) +1 }}] / ${{max(1,$index)}}";
