CPI test failed: unknown MPI error.


The FDTD solver stopped working. I ran the configuration test and got this error:

Is this a license problem? I can start FDTD but I can’t run the solver. With license issues I’ve seen before I couldn’t start FDTD at all.

Version 7.11.1584 Parameter Sweep "No data set was found for the result:..."

For Windows OS:

  • Try to check if both of the MPI components are installed on your system.

  • If it’s not installed you can install these components manually as described here:
  • Try to check your resource configuration and choose a different MPI to run the application, ie. use MPICH2 instead of Microsoft MPI or vice-versa.
