Insulation

If I want to model the heat transfer through insulation materials like aerogel or mineral wool. Is there a better way to to that than to assign material properties like conductivity, heat capacity and density to a domain (and apply radiation, convection on the boundary)? Should I instead use the "heat transfer in porous material" and if so, what is the difference?

Hei

I would say if you know the material property, this is the easiest way, porous material implies different species, and in your case it adds CFD that means quite some extra computational needs. But if you are interested in the air "convective flow" through mineral wool, probably, the complex way it could give some insights, but start with a small cube, not a full house

Good luck
