CONVERGE showing this error after 4hr of running

daizy · April 3, 2017, 01:08

MPI Application rank 8 killed before MPI_Finalize() with signal 9.
This is the error I am getting in the log file. I am using my company's cluster in japan for running the case.
Anyone having any idea hoe to resolve it.

Thanks a lot.

Hi daizy,

This error can occur when a pointer points to a location in memory outside the program space.

Are you using UDFs? If your udf is trying to get a value from something which has not been initialized, this error might occur.

Is something happening with the mesh at the simulation time when this error occurs? For example grid scaling or some embedding just started. The machines that you are running on, might not have enough space to handle the increased mesh size.

Hi Yajuvendra,
Thanks for your reply. I rectified the error, it was due to UDF and also storage on my disc at cluster was low, that is why I was facing this error.
Now I have completed the simulation.
Thanks.
