Hello,

I am a total newbie to firedrake.  I am trying to solve a coupled multiphysics system described by 4 PDEs & 1 algebraic equation.

I am totally new to numerical PDE solving.  I would like to avoid formulating my problem in the weak-form if possible.  People recommended OpenFOAM to me, as the codes are written in nearly the same way they are mathematically cast.

However, walking through firedrake tutorials, I see that there is a need for formulating the problem in weak-form.  The truth is  I don’t know how to do this.  Do I have to learn this art, or is there a workaround recommended ?
