In this PR, we are adding the ability to separately control the number of max pressure iterations in the predictor and corrector stages of the time integration. This has been tested on the
fds/Verification/Pressure_Solver/dancing_eddies_tight_no_precon.fdscase and the number of pressure iterations dropped from about 400k to 250k and the results still look fine. The speedup for this case was about 25% for the whole simulation.Here is a working input file:
