How to set the BC for coupling surface in Ansys
 

Hi, dear all , I am using Ansys to do thermal analysis (FEA). I have two material (solid and fluid seperately) in my model. The fluid zone is sealed in the solid zone. I have set up bc for the solid zone. but I am not quite sure how to set up bc for the fluid zone, do I need to do so? I know in fluent is automatically done by the software ........any hints will be helpful...

I have not done any such simulation, but in my opinion, if you set BC for the fluid zone, there would be conflicts between the BC and the automatically calculated values.
