@Martin, 

If you are only running on the local computer (1 computer), you can run without MPI. Running with 400 threads (-t 400) on the local computer (localhost) will take up 13 solve licenses (400/32). Ensure that you have 400 threads on the local computer and you are not oversubscribing the number of threads that what is available on the local machine.

#try running without '-use-solve' argument
/opt/lumerical/v241/bin/eme-engine -t 400 simulationfile.lms
/opt/lumerical/v241/bin/fdtd-engine -t 400 simulationfile.fsp

You can check the running processes with top. 

#run from terminal
top -H

With the (-H) argument, should show each eme engine process/cpu thread.
