Hello Everyone,

I've been working on Ansys Fluent and now switching to Star ccm+. During a simple simulation of heat tranfer in a fin by natural convection, I came across two kinds of solid energy models-segregated and coupled. I'm clear with segregated and coupled flow models, but unable to find difference between solid models.

Can someone explain me the theory and difference between segregated solid energy model and coupled solid energy model?

Coupled solid energy means you solve the solid energy equation at the same time as the other equations.

Of course there's not many reasons to do this, since the solid zones are always disjoint from the fluid zones. The only overlap is at the solid|fluid boundary.

Btw notice there is also a segregated/coupled fluid energy treatment.

Fluent doesn't distinguish between solid energy or fluid energy equations and uses the same formulation for both.
