I was reading literature on PDE (all three forms) and I found General (or coefficient) form is much easier to use than the weak one. I was wondering if there are anythings which we cannot perform using General/coefficient form and we must use weak form? Or we can do all what we want via an easier formulation?
As an example, if I want to modify the built-in continuity, momentum equation-we can simply make changes in "gamma" and "f" using general form which will be much easier instead of formulating a new continuity, momentum equation using weak form.
I want to know whether there are any limitations in using general form and we must take help from the weak form?
