BuildFESurfRHS

Calculates the divergence of a vector field over a surface. It is designed to calculate the surface integral of the vector field (gradient of the potential in electrical simulations).

Builds the surface portion of the RHS of FE calculations where the RHS of the function is GRAD dot F.

Detailed Description

Input

• A FE mesh with field vectors distributed on the elements (constant basis).

Output

• The Grad dot F
