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; } } |
