possible yes, but not within SimScale. The focus of material constitution and change of phases, growth, nucleation, dissolution, precipitation growth etc. is a very complex solid kinetic calculation. You can perform this with other software packages like I do in my Ph.D. but I think that they will not buy such software license for only one user and in addition they would need to have an expert in that topic (maybe they have one but I don’t think so based on the fact that this is not a big area of interest in general) in order to provide good results.
At last I want to mention that I am not a SimScale member so maybe they have already something available because right now I read this thread: What is the Transport Equation?
