Under-relaxation of p_rgh in fireFoam?

cryabroad · May 8, 2020, 01:00

Normally in solvers I see a line like

Code:

p.relax();

. I was looking at the solver fireFoam and specifically its pEqn.H file, but I didn't see such line for p_rgh. Does this mean that even if we put some under-relaxation factors for it, it is not working? All the tutorial cases use an under-relaxation factor of 1. Or maybe the under-relaxation is done somewhere but I missed.

Thank you!

Anyone? Still waiting for someone to shed some light on this.
