Dear All,
I am working on electrical modeling which I cannot change divergence to matrix form to solve it with finite difference or finite element, anybody can help me?
J Current density
E Electrical field
I Current source
J = σE (1)
J = ρ^(-1)1 E (2)
E = −∇v(x,y,z) (3)
∇ · J = I δ(x − xp) δ(y − yp) δ(z − zp) (4)
∇ · (ρ^(-1) ∇v(x,y,z)) = −I δ(x − xp) δ(y − yp) δ(z − zp) (5)
question is how to solve equation (5) with FD and / or FE methods?
Appreciate your help.
