Can anybody help me to do simulation of collapse of granular column submersed in in a liquid pool? Is it possible in CFDEMcoupling-public?
I have trying running a dam break problem of CFDEMcoupling in am getting an error. If anyone can help me to resolve the issue then i will be grateful.

mpirun was unable to find the specified executable file, and therefore
did not launch the job. This error was first reported for process
rank 0; it may have occurred for other processes as well.

NOTE: A common cause for this error is misspelling a mpirun command
line parameter option (remember that mpirun interprets the first
unrecognized command line token as the executable).
