Temperature field started diverging

Using SimScale Thermal
1

Hi guys,
I’m having trouble with my simulation. I am currently completing an assignment in which I need to run a simulation on an enclosure with an exhaust fan located on the right. The Temperature field diverging error appears, this is the exact message:

Temperature field started diverging. Please check the mesh quality near the reported location and try refining the mesh. If the problem occured near a boundary, please check the boundary conditions. Temperature = -132863 at position: (0.08682 m, -0.1588 m, 0.03793 m).

I am unsure why this is happening as my mesh appears to be fine, and I haven’t changed any temperature settings. Any help would be greatly appreciated! I am pretty new to simscale as this is my first real project. My project can be found here: Any help would be greatly appreciated! I am pretty new to simscale as this is my first real project.

Thank you in advance

Hi there, thank you for using the forum!

This issue is probably mesh related. Keep in mind to always check these two pages when divergence occurs:

These contain some valuable tips in order to locate the problematic areas that need refinement :slight_smile: The point that the error message indicates can also be helpful. :smiley:
For this case, another concern is the compressibility that was automatically applied as you are using the original version of the Conjugate Heat transfer analysis type. I will create a run to check this, and be back when I have news!

Best regards,
Fillia
