Error in FDTD

Any idea why my simulation crash every time that I try to running?Its a hardware limitation?(My laptop memory capacity; maybe)

Thanks in advance…


You can check first check the simulation requirements by clicking the “Check” button and selecting “Check simulation and memory requirements”. Here is a screenshot for one my simulation:

Just ensure that you have sufficient memory for the initialisation, meshing, simulation and data collection.

Best Wishes,



Hi @rod
Additional information about resource configuration you can find here:
I guess that something is going wrong with the msmpi engine. A lumerical’s application engineer had started a topic about Manual install of .Net 3.5, MS Mpi & MPICH2 Manual Install of MPI framework on Windows. But first ,as @vivek already said check the simulation requirements.

Best regards.
