I constantly meet same 'engine error' when running parameter sweep. The file is completed and auto-shutoff is met. Is there any possible solution to this problem?

The error log detail is as followed:

[proxy:0:[email protected]] ..hydrautilssocksock.c (827): write error on 4; errno: 232

[proxy:0:[email protected]] ..hydrapmpmiservpmip_cb.c (503): stdin forwarding error

Seems to indicate issues with the MPI. Try to check your resource configuration, which MPI are you using? Is the simulation file stored on a local hard drive or a network drive? Try to 'Continue' the job/s that have stopped or 'Restart' if the sweep does not take too long to run. This should also run the sweeps below/after it.

Thank you for answering my question.
My computer uses Windows operating system. I currently am using Intel MPI, but the engine error also occurs when using Microsoft MPI. However, the error log displays different contents. It is probably somthing like ' fatal error code _0'. I don't quite remember. The engine error appears less frequently under Intel MPI.
The files are stored locally.
Only 'Restart' and 'View job details' are clickable when I right click for details and 'Restart' gives no response.
I now suspect it may be a problem of my computer that I don't quite understand.

Try to use Local Computer as your Job launching preset and set the threads according to how many logical processors are on your machine. /forum/discussion/24720/ansys-insight-fixing-mpi-related-job-error-when-running-lumerical-simulations.
Hope this helps.
