A more thorough convergence check

A solve now keeps iterating while it is still settling, and a result is accepted only when it has converged and, in a model with rack heat, its heat balances. Some runs take longer, and some that would have been delivered before are now refused.

Improvements to meshing small gaps

Can change results

The minimum gap between objects now reaches the mesher more accurately, which gives better cells between objects that sit close together. Meshes and results can differ from earlier runs.

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.
