Hello everyone,

I'm trying to use parallel computation(mpiexec) and immersed boundary method to simulate wind turbines.

I did succeed when I submit a case that use 16 cores,which is very stable:

mpiexec -n 16 windPlantSolverFAST

But I failed when I submit it using 32 cores:

mpiexec -n 32 windPlantSolverFAST

The result of slurm standard output (#SBATCH -o log.xxx)told me that there was something wrong with the address, whose output was:

--------------------------------------------------------------------------
mpiexec noticed that process rank 10 with PID 23013 on node TUMWHST-WE102 exited on signal 11 (Segmentation fault).

I suppose that the reason for the crash is that the immersed boundary was "cut". That means, one immersed boundary was divided into two pieces by mpiexec, the two pieces were calculated by different cores -- then it crashed. But, it is only my guess. Does anyone have some ideas? Thanks very much!

Best regards!
