Heat transfer in thin aluminum casing

Please login with a confirmed email address before reporting spam

Hello,

I would like some guidance on how to set up heat transfer for a thin aluminum casing.

My model has two solid blocks that generate heat. They are enclosed in a 1mm casing. I would like model the casing using a thin layer or shell layer physics instead of modeling the geometry of the casing to prevent working with very small meshes.

I am struggling to set up the conduction and convection between the solid blocks and the casing and the casing with the environment

My questions are:

  1. should I use the "Thin Layer" under Heat transfer in solids or the physics "Heat Transfer in Shells"?

  2. I don't see an option to establish conduction between the layer/shell and the casing. The encased solid blocks show up as "insulated".

  3. With the thin layer, I don't see an option to set up convective flux over a boundary only over edges.

Thank you,

Renzo
