Issue not reproducible on my machine, using latest version of main. I am utilising latest version of Motor-CAD publicly available, 2024_2_2_1. Code executes successfully:

resulting output successfully used in TB:

This may be due to changes in Motor-CAD default behaviour in 2025 test release. This has a different default method for "Fluid Heat Flow Method" which results in different output files being written.

@jgsdavies can you please confirm which version of Motor-CAD was used that produced this error?

Trying out a fix: check if newer version of Motor-CAD is being used, and if so, ensure the old working heat flow method is used.
