We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hello Bob, thank you for cleaning up the duplicate posts. I couldn’t figure out how to delete them. The poor converged case is completely absent, meaning all my cases are converging nicely, as I mentioned. The temperature and velocity values at my control points remain stable. However, when I change the mesh, my results change inconsistently. I understand that it’s normal for results to change when the mesh is altered, but as I refine the mesh, the values don’t show a consistent decrease or increase. For example, my temperature values might be 430, 420, 418, and suddenly, as I refine it further, I see values like 402, and with more refinement, even lower values like 375K.
