Dear CFDEM users and developers,

I have installed CFDEM coupling software and run the case ErgunTestMPI to do run test.
It reports the following error: cannot remove '/home/ann/TEST/cfdemSolverPiso/ErgunTestMPI/log_run_parallel_cfdemSolverPiso_ErgunTestMPI_CFDEM': No such file or directory
Decoposing case.

(please see the attached screen shot)

Could you please tell me how to solve this problem?

Thank you in advance.

Ann
