Hello,
now that you give a more precise desciption of your problem, I
understand that you want to solve a dynamic equation.
I can only be of little help since I do not understand the part b) of
the algorithm you want to program.
I can just say that it is possible to program the equation :
> a) d/dt(Phi) + Spd*Norm(Grad(Phi)) = 0
the formulation would be :
Galerkin { Dt [ Dof{Phi} , {Phi} ] ; ... }
Galerkin { [ Spd[] * Norm[{d Phi}] , {Phi} ] ; ... }
and the resolution with "TimeLoopTheta" will be an explicit Euler
algorithm.
As I don't really understand your algorithm with b), I can't say if it
is possible to do it with GetDP. My feeling is that it is not currently
possible without modifying the program.
Regards,
O.C.
PS : if you manage to do something nice with the level set equations,
maybe you can post it later or put it on the wiki ?
