Temperature diverging for finer meshes but not for coarser meshes

Link to project

Pretty much the title. I first noticed when running a simulation that had a mesh with automatic boundary layers, then again when I ran a simulation with a mesh that was set to fineness of Fine rather than Moderate. I get results for the Moderate mesh but a diverging temperature for both the Fine mesh and the Moderate mesh with automatic boundary layers.

Hey there!

We always recommend to use the Standar mesher, as it is more robust.

The Hex mesher sometimes throws this types of weird behavior.

Thank you! I’ll try that.
