Hi,

I have already answered this in post #6 above. I don't know about FireFoam, but as long as you're using "perfectGas" model the psi_ is updated by invoking the psi(p, T) function in...

Dear Foamers,

I found the answer to some of my questions:

1. rho update process:

Yes, this is how density is updated when the thermo.rho() is invoked.

2.1 the psi calculation procedure:
