How do I solve this error?
A setup with 2 regions is being used in a single-region analysis type. Please make sure that all regions except for one have an Advanced Concept assigned to them.
If I delete the bodies in Cad edit mode, I am unable to assign materials/ topological entity set parameters to it.
Hi, and thanks for using the forum!
In the Convective Heat Transfer simulation, you will be analyzing the fluid only, thus you need to delete all the solid parts.
In the Heat Transfer simulation, you will be analyzing only the solids, thus you can not have the fluid region.
If you want to analyze the conduction in the solids and the convection in the fluid at the same time, then you should perform a Conjugate Heat Transfer simulation.
