      ,Can you try to run the mwp.fsp example from this article ? If the error happens with the example, mwp.fsp, try to run the simulation using Local Computer as your Job launching preset. See this post on running jobs without MPI. Otherwise if the issue only occurs with your simulation, check and make changes to your simulation/project. n
