[Gmsh] Formulation GetDP

[Juliana]

Good Afternoon!

In an electrostatic problem in the formulation of the exercise was described in
the following expression:

Equation {
Galerkin {[epsr[] * Dof {d v} {d v}]; In Vol; Jacobian Vol; Integration Int;}
GlobalTerm {[Dof {Q-} / eps0, {V}]; In Grouped;}
}

I began studying the GetDP did not understand how to get this 
[epsr[] * Dof {d v} {d v}] and [-Dof {Q} / eps0, {V}].

How to develop the equations in GetDP?
GetDP solve various kinds of applications such as development.

Thanks,
Juliana.
