Hi guys,
I have created a transformer model and want to simulate its temperature distribution under natural cooling. I need to set convection coefficient for all the EXTERNAL surfaces to be 5 W/m2K, but as I tried, it turned out I cannot select only the external surface of the object, but only the bigger surface that contains the external surface on a object.
For example, for a simple model like below, If I want to select all the external surfaces for convection setting, I need to select the ractangular ring between the two objects. However, when I click the ring region, the whole rectangular surface is selected. As I tried before, the software will not directly neglect the convection of that contact surface, but that is not the real world case.

It can be done by updating the geometry in SpaceClaim in any of the following 2 ways -
Use "Share Topology" for the geometry
OR
Use "Split" to split the upper surface of the lower body about which convection needs to be applied.
