Hi @FedericoCipolletta ,
Thank you very much for your reply. I have tried to remove min-fact and max-fact, but still got the same error.
Regarding the openmp backend, it really makes me crazy. Whether I use or remove the following command, I get the same error (RuntimeError: Minimum sized time step rejected).
[backend-openmp]
cc = gcc
cblas-mt = libmkl_rt.so
gimmik-max-nnz = 8192
I also failed to use openmp as backend to run the example case (see here, please), and I got another error.
Things are really weird. I am not sure whether the RuntimeError: Minimum sized time step rejected error in this NACA0021 case is caused by the same reason as the example case.
Besides the min-fact and max-fact, is there any other difference between the config you managed to run and mine?
Thank you for your help.
