Question About the pressure under-relaxation in fireFoam

hz283 is on a distinguished road
Dear All,

In the solver fireFoam, I found that the p_rgh.relax() is not used in pEqn.H, and all other combustion solvers in OF211 have not such relaxation treatment. However, in the compressible solvers, they have it. Could anyone please give some explanations about why the pressure relaxation is not used in all the combustion solvers?

Second question: the relaxationFactors defined in fvSolution dictionary are for *.relax()?

Thank you very much.
