finishes before convergence and last sweep

Antony

Dear all, I run a steady state problem with Phoenics. I just can't understand why it finishes before the LSWEEP and before it satisfies the RESREF criteria (with RESFAC = 1E-3). The (res sum)/resref in the result file are still big (about 1.5 E+01) for some variables.

When I change the RESFAC from 1E-3 into 1E-4, it can run until the last sweep although only one of PHI variables has (res sum)/resref > 1.

I paste below two pieces from result file which indicates the termination before LSWEEP and before the criteria is satisfied.

Regards, Antony
