I want to be able to assign a material to the body so I can do a transient simulation and observe how the cooling changes with change of the material. Simple illustration provided below. No matter what I try, Discovery is letting me know about issues, with no guidance on how to resolve it: there is interference, remove interference, remove sharing, conducting non-slip wall assigned a temperature, etc. &lt;br&gt;&lt;br&gt;Is it even possible to simulate this in Discovery? If yes, how should I set up my model?
