abeqhorie is on a distinguished road

I want to simulate anodized heatsinks. How do we set the heatsink as anodize material?

Thank you.

Hi abeqhorie,

anodization is a surface treatment so the only boundary condition that would change is the roughness or radiation properties of the surface. The material itself does not really change, just in a very thin surface layer that shouldn't influence the overall behaviour. If the surface thermal conductivity changes then you can apply a contact resistance.
But all these values depend heavily onthe process and after treatment you had. For example anodizing and then having a surface paint on it which reflects and/or emits radiation differently than the other color etc.

I hope this helps,
