Minimum pressure limit for compressible solvers?

Is there any way to set a min absolute pressure limit for compressible solvers?

Hi,

yes, have a look a rhoSimpleFOAM.

The function is max(p,yourMinValue);

Kind Regards,
Christian

Hi,

I am also interested in this topic. I am not able to find the limit for p in rhoSimpleFoam.

Thanks

Robert

Hi Robert,

I was able to do it, but it did not help me in my problem much
You have to do it just like it is done for rho

read pMax and pMin from the fvSolution (ref:createFields.H)

then you can use these max and min values in your solver
