Hi,

I am simulating a stirred tank reacrtor. After a few rotations of the impeller I have injected 7000 particles and I am tracking them with DPM. I am saving the case and data files every 2 ts. But, every few time steps the while saving the data file, it stops and gives me this message:

"Host receiving summary from compute node zero.
Writing "D:\Parisa\FLUENT\Ny mapp (3)\DPM\dpm-3-01996.dat"...
MPI Application rank 2 exited before MPI_Finalize() with status -1073741819
999999 (..\src\mpsystem.c@1149): mpt_read: failed: errno = 10054
999999: mpt_read: error: read failed trying to read 4 bytes: Invalid argument
The Parallel FLUENT process could not be started.
Error: Error writing "D:\Parisa\FLUENT\Ny mapp (3)\DPM\dpm-3-01996.dat".
Error Object: #f"

Then I have to close everything and change my parallel cores from 4 to 3 and open my case and data from one ts before crashing. However, it happens again with 3 cores and then I have to change to 4 again, it happens all the time and I have to switch between the number of cores every 10 or so ts!
Can you please help me to understand and solve the problem?

Thanks,
Parisa
