Hello
ALE is certainly a good approach, particularly if you have larger deformations. I cannot confirm your formula, bacause I havent to now used it myself, but from the help I beleive you are right.
I have learned to carefully check every variable, as there is not always the full physical formula written out in the doc (COMSOL would need to rewrite a full physics book, but I still beleive they should).
This is my only concern with COMSOL, I'm still not 100% used to COMSOl's way to not write indexes, nor even integrals , in their formulas, and GUI's.
Good luck
