Using both external and internal volume in one design

[igaviano]

Hi @Owura, thanks for posting on the forum and welcome to the SimScale Community

@Owura

I want to know whether the results i got is a true representation of the right thing i have done as i see some extreme temperatures I am not so convinced they might be true

Since your project is not shared with support, unfortunately we can’t pinpoint what the exact issue is - take a look here to know how to share your project. However, from your description, this does sound like a divergence issue, in which case these resources might be helpful:

• How to Check Convergence of a CFD Simulation? | SimScale
• Divergence in Simulation: How to Tell When and Where? | SimScale
• How to Check and Improve Mesh Quality | SimScale

I also often see these “extreme temperatures” appearing when there’s no channel for the heat to flow - for instance, if the domain’s walls are defined as “adiabatic”.

Hope this helps!

Cheers
Igor
