How to fix ‘engine error’ when running simulation or sweep.

Check if your simulation has enough RAM installed to run your simulation job (FDTD simulations) as described from the article:

Then try the suggestions here:

Windows

  1. Make sure that the MPI framework you are using as your job lauching preset is installed.
  2. Otherwise If one or any of the 3 is not installed, please install manually as shown below:

Test and try to resolve the problem

  • Download and run a simulation using one of our sample file, paralleltest.fsp (280.8 KB)

  • Try to run the simulation by changing the job launching preset to:

On Windows:
When using MPICH 2 and prompted for authentication as shown here:

Works using a different MPI framework

On Windows:

If the error persist on a certain design projects/simulations

  • check the simulation design and make changes
  • check the user account access on the folder where the simulation file is stored
  • try to store/save the simulation to a local drive and folder. i.e. your Desktop
  • refer to this KX post on memory requirements, Tips on running FDTD simulations
