When I run my simulation in Lumerical DEVICE, it shows an error entitled `engine error` after reaching the simulation to 100 percent. When I right-click and chose 'job details`, it only shows the directory of a file named `device-engine-msmpi.exe` and the simulation file directory. I changed the simulation file directory to windows drive but it was not fixed. I also uninstalled Microsoft MPI and re-installed it but the problem still exists. The error message screenshot is attached.
Any suggestions would be appreciated.
Dear Kianoosh Karimi , may be this thread in Lumerical Knowledge base could help you:
https://kx.lumerical.com/t/engine-error-microsoft-mpi-doesnt-work/66728/9
The user dealed with MPI by Windows, but finally the problem was related to MATLAB integration status . So may be you have Matlab installed and it could be causing the problem.
The person from Lumerical indicates that 3 MPI files must be installed (these from Lumerical, Microsoft and Intel). Another source of problems could be the lack of RAM resources.
I also thought about the idev. filesize... or the path size itself, sometimes I had problems with that (not with Lumerical but with other applications).
Hope it helps!
