Henry Weller a1c8cde310 rhoSimpleFoam: added support for compressible liquid flows
rhoSimpleFoam now instantiates the lower-level fluidThermo which instantiates
either a psiThermo or rhoThermo according to the 'type' specification in
thermophysicalProperties, e.g.

thermoType
{
    type            hePsiThermo;
    mixture         pureMixture;
    transport       sutherland;
    thermo          janaf;
    equationOfState perfectGas;
    specie          specie;
    energy          sensibleInternalEnergy;
}

instantiates a psiThermo for a perfect gas with JANAF thermodynamics, whereas

thermoType
{
    type            heRhoThermo;
    mixture         pureMixture;
    properties      liquid;
    energy          sensibleInternalEnergy;
}

mixture
{
    H2O;
}

instantiates a rhoThermo for water, see new tutorial
compressible/rhoSimpleFoam/squareBendLiq.

In order to support complex equations of state the pressure can no longer be
unlimited and rhoSimpleFoam now limits the pressure rather than the density to
handle start-up more robustly.

For backward compatibility 'rhoMin' and 'rhoMax' can still be used in the SIMPLE
sub-dictionary of fvSolution which are converted into 'pMax' and 'pMin' but it
is better to set either 'pMax' and 'pMin' directly or use the more convenient
'pMinFactor' and 'pMinFactor' from which 'pMax' and 'pMin' are calculated using
the fixed boundary pressure or reference pressure e.g.

SIMPLE
{
    nNonOrthogonalCorrectors 0;

    pMinFactor      0.1;
    pMaxFactor      1.5;

    transonic       yes;
    consistent      yes;

    residualControl
    {
        p               1e-3;
        U               1e-4;
        e               1e-3;
        "(k|epsilon|omega)" 1e-3;
    }
}

OpenFOAM Configuration

The main OpenFOAM settings are located in the parent etc/ directory. The bash and csh shells are supported and to configure OpenFOAM source etc/bashrc or etc/cshrc respectively which source the following files in the config.sh or config.csh respectively:

  • settings: core settings
  • aliases: aliases for interactive shells
  • unset: sourced to clear as many OpenFOAM environment settings as possible
  • mpi: MPI communications library settings
  • ensight: application settings for EnSight
  • paraview: application settings for ParaView
  • scotch: application settings for compiling against scotch
  • metis: application settings for compiling against metis 5

The config.*/example directories contains various example configuration files for the corresponding shell:

  • compiler: an example of fine tuning ThirdParty compiler settings
  • openmpi: an example of fine tuning openmpi settings for OpenFOAM
  • paraview: an example of chaining to the standard config/paraview with a different ParaView_VERSION
  • prefs: an example of supplying alternative site-defined settings
