Hi,

I would like to adjust the current buoyantPisoFoam solver, so that rho is independent of the current pressure. I thought, it would be easiest to adjust in equationOfState the perfectGas files (I included the base pressure) ...

so basically the calculation in perfectGasI.H for rho looks like:

return p0_/(R()*T);

unfortunately, it seems to have no influence on the calculation.

The thermal properties are

thermoType hRhoThermo<pureMixture<constTransport<specieThermo <hConstThermo<perfectGas>>>>>;

and the mixture is adjusted with an additional entry for the base-pressure p0_.

Would be nice, if anyone has some suggestions.

Fabian

Hi,

i have a similar problem, did you have any success with changing the buoyant solver?
