Hello,
i am just beginning to learn and work with getdp (with gmsh). After
trying some of the examples from the wiki, now i try to understand the
formulation. Later I have to solve a problem in 3D with coupled
inductors and ferrite.
Now I stop at the electrostatic example mStrip.geo & mStrip.pro. There
is the formulation:
Equation {Galerkin { [ epsr[] * Dof{d v} , {d v} ]; In DomainCC_Ele;
Jacobian Vol; Integration GradGrad; }}
My questions:
1. Can Dof{d v} also be written as Dof{Grad v}? - Where is this
documented? (I searched the mail-list for it)
2. Means Dof{x} that x is the unknown?
3. In this case (2.), why is {d v} repeated after "Dof{d v},"?
So far for my first posting. I would be glad about your answers.
Best regards
