Hi All,

I am trying to create a simulation for an electronics enclosure that is vented in air and cooled via natural convection.

I am using solidworks to create the geometry and ANSYS meshing to create the mesh to go into fluent.

My question is what are your recommendations for workflow to make sure that the model comes into fluent with the right contact regions and interfaces for heat transfer?

I am having a hard time visualizing if the right surfaces are being chosen by ANSYS meshing and fluent when creating these interfaces. I create a volume in solidworks by making a large box(the air) and then creating a cavity from all the parts in the assembly. In solidworks I have removed much of the complexity of the parts and bonded several parts of the same material together, before ANSYS sees them. Still, gaps are overlooked and determined as contact surfaces in ANSYS.

Is it best to define all these contact surfaces in solidworks as named selections?

Another question, do I need to have only one target surface for one contact surface?

Thanks for the help.
