When I used MPI to calculate a DISI case, I found huge difference in pressure prediction when different number of processors are used (8 VS. 32). Using less number of processors results in higher peak pressure (1 MPa higher) and advanced ignition timing. Does anyone meet the similar situation, is it reasonable?

Thank you very much for your attention and help.

Best regards,
Yaopeng

OK, I know now. The prediction difference is ascribed to the ECFM model.
