Hi,
In my simulation, nonlinear solve with the trust regtion method got
stagnentafter linear solve (see output below). Is it possible that the
method goes
to inifite loop? Is there any parameter to avoid this situation?
0 SNES Function norm 1.828728087153e+03
0 KSP Residual norm 91.2735
Linear solve converged due to CONVERGED_ITS iterations 1
Linear solve converged due to CONVERGED_RTOL iterations 3
1 KSP Residual norm 3.42223
Linear solve converged due to CONVERGED_STEP_LENGTH iterations 1
Thank you in advance,
Nori
