I used CFD for simulation of two different wall materials. Both are thermal mass. For one material, even with less thickness; number of nodes is more than the other material. Could this be related to the thermal properties such as conductivity? Let's say the wall material with less conductivity results in more nodes? In brief, would like to know how the number of nodes is chosen in CFD? If there is any reference about this that I could read, I would appreciate someone could introduce.
