Hello all,
I am starting to work with Fluent to model convection heat transfer (Natural convection) between a solid which is generating heat and a surrounding volume of air (the volume is fixed). I have tried two methods so far
1. defining these two bodies as a single part and by doing so I get a conjucate mesh on the boundry (between solid and fluid)
2. deining these two bodies as a individual parts, the individual faces of the solid as a named selection, upon updating it in Fluent I get respective shadow walls.
Now, in both cases I have no successes so far. I know there is a problem in wall BC definition. Now I have the basic settings right. Can you tell me some reading/video material where I could understand the wall BC definitions better(esp for thermal problems).
one more question. I have worked relatively a lot in Ansys Thermal, can I model the fixed volume of air around the body as a 3D Model and simulate it in FEM? Will it make good sense? because the air in our case is not moving around and the volume might also be same because its a closed environment.
Looking forward your suggestions!
