Release 2026.10.23.7

Improvements to how a finished run completes

In rare cases the solver could stop responding just after a run had finished, which held the job and could end it as a failure even though its results were complete. CoolSim now recognizes this and completes the job with its results. Results themselves are unchanged, and runs that finish normally are not affected.

How we know it’s right
Every CoolSim job is meshed with Ansys Icepak, solved with Ansys Fluent, and has to pass the same checks before its report is sent. What those checks are, what they don't prove, and how to check a report yourself.
