Hi Mike:

I would suggest trying a regular parallel run to rule out issues with MPI, and/or test a very simple case in parallel, such as a closed reactor.

ANSYS Forte 2024R1 uses MPI 2021 and MPI 2018, so I imagine Chemkin would be the same.  To be safe, you can try installing the MPI that comes with the 2024 release:

Best Regards
