Hello forum.
a steady state, incopressible run.
Su2 starts, and calculation goes on up to N iterations, or convergence, when I issue

mpiexec.exe -n <x> SU2_CFD_MPI.exe Su2_20250101120547622.cfg

when x = 1,2,3,4,5,7,8.
But, for x = 6, i.e.

mpiexec.exe -n 6 SU2_CFD_MPI.exe Su2_20250101120547622.cfg

the solver stops, and the console output is:

"

I attach a link to the .cfg and mesh file.

Why?

Grazie mille

For sure the fact that the solver stops depends on the number of cores, but in principle, at the very beginning, it seems to be due to the present one/two distorted elements in the mesh. I will check.
