Reply To: Segmentation fault for OpenLB 1.5


What’s more, when I ran it by serial mode (MPI mode off), there was still a problem:
[prepareLattice] Prepare Lattice …
Primary job terminated normally, but 1 process returned
a non-zero exit code. Per user-direction, the job has been aborted.
mpiexec noticed that process rank 0 with PID 26350 on node csk060 exited on signal 11 (Segmentation fault).

So you ran the sequential mode in MPI here?

Can you recompile the failing non-MPI case in debug mode and post the backtrace? (start e.g. in gdb and print the backtrace from there using bt).
