Hello Olivier,
thanks for the follow-up. Yes, I did see your comment about the following:
Galerkin{ [ Spd[]* Norm[{d Phi}] , {Phi} ] ... }
I guess it is only different from what I was trying in the Dof{} term, i.e.:
Galerkin{ [ Spd[]*Dof{Norm[{d Phi}]} , {Phi} ] ... }
However, if I leave out the Dof{} term, won't that mean that Phi is no
longer treated as a variable to be solved for, but rather as something
given already? In other words, I won't be solving the right problem?
Thanks,
Matt Koch
