[steady-state]

Good Day Everyone,

Just wondering if anyone can give me some advice on how to model a particular conjugate heat transfer problem. I've attached a paint image of the basic geometry but keep in mind, the actual geometry is in 3D with no real symmetry plane. Both sides of this completely sealed device are covered in fins and eventually I want to be able to evaluate fin design vs internal temperatures.

Electronic components generating heat are mounted on a pedestal connected to the exterior casing. How can I use ANSYS to solve for conduction to the outside case and internal circulation? I realize its a CHT, but I can't figure out how to adapt when natural convection is present.

Eventually I want to use the directional heat flux/temperatures of the outside case to evaluate the outer fins in a natural convection external flow. How can most easily use the output from one analysis as an input to another analysis?

Any discussion or help would be greatly appreciated.

Thanks,
