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:
- Make sure that the MPI framework you are using as your job lauching preset is installed.
- 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:
- Local Computer
- or MPICH2
- or Intel MPI on Windows only
When using MPICH 2 and prompted for authentication as shown here:
Works using a different MPI framework
- uninstall the non-working MPI from your machine
- if this is not installed,
rebootyour machine and
installas shown here: Install Microsoft .Net 3.5 and MPI framework
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.
