Hello there,
I am trying to formulate "s*Norm(Grad Phi)" vs. "v*Grad(Phi)", whereby
s is a scalar speed and v is a vector velocity - parallel to
Grad(Phi). The formulation with the velocity seems to work just fine:
Galerkin{[Vel[]*Dof{d Phi},{Phi}];In Vlm;Integration Int;Jacobian Jac;}
However, the formulation with the speed crashes with a parse error on "[":
Galerkin{[Spd[]*Dof{Norm[{d Phi}]},{Phi}];In Vlm;Integration
Int;Jacobian Jac;}
All variations of this, such as
Galerkin{[Spd[]*Dof{Norm[Grad Phi]},{Phi}];In Vlm;Integration
Int;Jacobian Jac;}
or
Galerkin{[Spd[]*Dof{Norm[d Phi]},{Phi}];In Vlm;Integration Int;Jacobian Jac;}
die a parse death as well. Can anybody help me implement the Norm
formulation? This is in support of the Stefan Problem and Level Set
Method I asked about before.
Thanks,
Matt Koch
