Hello, I have a model of a room which contains heat sources, and I meet the following error code.

Error: Build Grid: Aborted due to critical error. 
Error Object: #f

To my understanding, this is affected by the mesh quality, but as seen in the attached images, the skewness and aspect ratios should not be a problem. 

Where might I look to find the source of this problem? I'm at my wit's end.

What does the section plane look like? Cell quality means your cells are OK, however mesh quality also includes mesh resolution within a domain.

The section plane through my heat sources look strange in my opinion. Should the mesh inside my heat sources and the room line up (have shared topology) or is this not the issue?

[Rob]

It doesn't need to line up, but does need to not overlap: ideally it will line up. You've not split the room with the contents. 

[ahan20]

This should be done in space claim, right? How would I do this?

[Rob]

Yes, look at "Share Topology". 

[ahan20]

Share Topology does not recognize the sides of my heat sources.

Check for duplicate bodies. You may also want to update to 2025R1 as Share Topo has been improved significantly.
