Theory and Basics

Formulations

The basis equations:
(1)           rot e = 0
(2)           div d = ρ
(3)           d = ε e

Constitutive relations:
(4)        j = σ e

Boundary conditions:
(5)        n x e  | Γ0e = 0
(6)        n * d  | Γ0d = 0

Electric scalar potential formulation:
(7)        div ε grad v = - ρ with 
(8)        e = -grad v

Electrodynamic weak v-formulation:
(9)        ( d/dt(-ε grad v), grad v’ )Ω + (σ grad v, grad v’ )Ωc = 0, 
                for all v’ element of Ω
