Different number of core for CFD and DEM in parallel running

Dear all,

I'm running the EngunMPI tutorial case on HPC using 40 cores and I detect that the number of cores for DEM and CFD parts the same, but in is not good becouse CFD parts is very sensetive for number of cores. In this situation I wanted to run DEM using 40 cores and CFD -5 cores. Is it possible to run CFDEM in this way?

Best regards, Furkhat
