Adds overset discretisation to selected physics:
- diffusion : overLaplacianDyMFoam
- incompressible steady : overSimpleFoam
- incompressible transient : overPimpleDyMFoam
- compressible transient: overRhoPimpleDyMFoam
- two-phase VOF: overInterDyMFoam
The overset method chosen is a parallel, fully implicit implementation
whereby the interpolation (from donor to acceptor) is inserted as an
adapted discretisation on the donor cells, such that the resulting matrix
can be solved using the standard linear solvers.
Above solvers come with a set of tutorials, showing how to create and set-up
simple simulations from scratch.
Some versions of lsof print the mount point (if remote) after the
script path:
/hosts/mymachine/OpenFOAM/OpenFOAM-plus.develop/etc/cshrc (mymachine:/home)
This now gets filtered out.
except turbulence and lagrangian which will also be updated shortly.
For example in the nonNewtonianIcoFoam offsetCylinder tutorial the viscosity
model coefficients may be specified in the corresponding "<type>Coeffs"
sub-dictionary:
transportModel CrossPowerLaw;
CrossPowerLawCoeffs
{
nu0 [0 2 -1 0 0 0 0] 0.01;
nuInf [0 2 -1 0 0 0 0] 10;
m [0 0 1 0 0 0 0] 0.4;
n [0 0 0 0 0 0 0] 3;
}
BirdCarreauCoeffs
{
nu0 [0 2 -1 0 0 0 0] 1e-06;
nuInf [0 2 -1 0 0 0 0] 1e-06;
k [0 0 1 0 0 0 0] 0;
n [0 0 0 0 0 0 0] 1;
}
which allows a quick change between models, or using the simpler
transportModel CrossPowerLaw;
nu0 [0 2 -1 0 0 0 0] 0.01;
nuInf [0 2 -1 0 0 0 0] 10;
m [0 0 1 0 0 0 0] 0.4;
n [0 0 0 0 0 0 0] 3;
if quick switching between models is not required.
To support this more convenient parameter specification the inconsistent
specification of seedSampleSet in the streamLine and wallBoundedStreamLine
functionObjects had to be corrected from
// Seeding method.
seedSampleSet uniform; //cloud; //triSurfaceMeshPointSet;
uniformCoeffs
{
type uniform;
axis x; //distance;
// Note: tracks slightly offset so as not to be on a face
start (-1.001 -0.05 0.0011);
end (-1.001 -0.05 1.0011);
nPoints 20;
}
to the simpler
// Seeding method.
seedSampleSet
{
type uniform;
axis x; //distance;
// Note: tracks slightly offset so as not to be on a face
start (-1.001 -0.05 0.0011);
end (-1.001 -0.05 1.0011);
nPoints 20;
}
which also support the "<type>Coeffs" form
// Seeding method.
seedSampleSet
{
type uniform;
uniformCoeffs
{
axis x; //distance;
// Note: tracks slightly offset so as not to be on a face
start (-1.001 -0.05 0.0011);
end (-1.001 -0.05 1.0011);
nPoints 20;
}
}
- suppress error messages that appear with zsh.
According to unset(1p), 'unset -f' unsets a function.
If the function was not previously defined, this is a no-op.
This is similar for zsh, but there it emits a warning if the
function was not previously defined.
- avoid 'local' in functions sources from etc/bashrc.
ksh does not support this.
- use 'command' shell builtin instead of 'type'.
Seems to be more consistent between shell flavours.
- use InfoSwitch to disable, or via static method.
- respect the state of the argList banner when deciding to emit
initialization information. Can otherwise end up with unwanted
output rubbish on things like foamDictionary and foamListTimes.
by combining with and rationalizing functionality from
turbulentHeatFluxTemperatureFvPatchScalarField.
externalWallHeatFluxTemperatureFvPatchScalarField now replaces
turbulentHeatFluxTemperatureFvPatchScalarField which is no longer needed and has
been removed.
Description
This boundary condition applies a heat flux condition to temperature
on an external wall in one of three modes:
- fixed power: supply Q
- fixed heat flux: supply q
- fixed heat transfer coefficient: supply h and Ta
where:
\vartable
Q | Power [W]
q | Heat flux [W/m^2]
h | Heat transfer coefficient [W/m^2/K]
Ta | Ambient temperature [K]
\endvartable
For heat transfer coefficient mode optional thin thermal layer resistances
can be specified through thicknessLayers and kappaLayers entries.
The thermal conductivity \c kappa can either be retrieved from various
possible sources, as detailed in the class temperatureCoupledBase.
Usage
\table
Property | Description | Required | Default value
mode | 'power', 'flux' or 'coefficient' | yes |
Q | Power [W] | for mode 'power' |
q | Heat flux [W/m^2] | for mode 'flux' |
h | Heat transfer coefficient [W/m^2/K] | for mode 'coefficent' |
Ta | Ambient temperature [K] | for mode 'coefficient' |
thicknessLayers | Layer thicknesses [m] | no |
kappaLayers | Layer thermal conductivities [W/m/K] | no |
qr | Name of the radiative field | no | none
qrRelaxation | Relaxation factor for radiative field | no | 1
kappaMethod | Inherited from temperatureCoupledBase | inherited |
kappa | Inherited from temperatureCoupledBase | inherited |
\endtable
Example of the boundary condition specification:
\verbatim
<patchName>
{
type externalWallHeatFluxTemperature;
mode coefficient;
Ta uniform 300.0;
h uniform 10.0;
thicknessLayers (0.1 0.2 0.3 0.4);
kappaLayers (1 2 3 4);
kappaMethod fluidThermo;
value $internalField;
}

- just check WM_PROJECT_DIR instead.
- provide a fallback value when FOAM_EXT_LIBBIN might actually be needed.
Only strictly need FOAM_EXT_LIBBIN for scotch/metis decomposition, and
when these are actually supplied by ThirdParty.
All other ThirdParty dependencies are referenced by BOOST_ARCH_PATH etc.
Can therefore drop the FOAM_EXT_LIBBIN dependency for VTK-related
things, which do not use scotch/metis anyhow.
snappyHexMesh produces a far better quality AMI interface using a cylindrical background mesh,
leading to much more robust performance, even on a relatively coarse mesh. The min/max AMI
weights remain close to 1 as the mesh moves, giving better conservation.
The rotating geometry template cases are configured with a blockMeshDict file for a cylindrical
background mesh aligned along the z-axis. The details of use are found in the README and
blockMeshDict files.
Uncommenting the patches provides a convenient way to use the patches in the background mesh
to define the external boundary of the final mesh. Replaces previous setup with a separate
blockMeshDict.extPatches file.
- this implies that jobControl is a user-resource for OpenFOAM.
It was previously located under $WM_PROJECT_INST_DIR/jobControl,
but few users will have write access there.
- an unset FOAM_JOB_DIR variable is treated as "~/.OpenFOAM/jobControl",
which can partially reduce environment clutter.
- provide argList::noJobInfo() to conveniently suppress job-info on an
individual basis for short-running utilities (eg, foamListTimes) to
avoid unneeded clutter.
- permit SYSTEMMPI user adjustments via
etc/config.{csh,sh}/mpi-system
This can be a convenient place for setting up SYSTEMMPI for OpenFOAM
without adjusting bashrc, prefs.sh ...
- add a USERMPI type. This represents any generic mpi implementation.
The user is responsible for supplying an appropriate
wmake/rules/General/mplibUSERMPI file and managing all settings.
This type of setup can be useful in combination with specific build
systems (SPACK, EASYBUILD, etc) or module systems for which the MPI
variant is part of the installed configuration.
- lazier evaluation of project name and version based on the directory
name. Avoids heuristics based on directory names unless really needed.
- cope with alternative directory locations.
For example, OpenFOAM+VERSION etc.
The combination of the two above appears to be sufficient to open up
the directory naming possibilities.
- additional -list-test option (tests for existence of directory).
- handle sourcing bashrc with a relative path (issue #383)
- handle sourcing from bash and zsh.
Still need manual intervention when sourcing dash, sh, or ksh.
- replace grep in etc/cshrc with sed only
- logical instead of physical path for WM_PROJECT_DIR (issue #431).
Doesn't seem to be possible for csh/tcsh.
* Continue using physical locations when comparing directories,
but not for the top-level FOAM_INST_DIR, WM_PROJECT_DIR.
- relocate WM_CC, WM_CXX overrides from etc/config.*/compiler
to etc/config.*/settings to ensure that they are left untouched
when etc/config.sh/compiler is sourced while making third-party
packages (eg, gcc, llvm, CGAL).
- provide fallback FOAM_TUTORIALS setting in RunFunctions
STYLE: remove "~OpenFOAM" fallback as being too rare, non-obvious
