Detailed Description

operator L is defined as L(B) = alpha B + beta*(divF) where F = div(eta(grad B - grad B^T) + eta I div B ) alpha and beta are constants. eta is a function of space. beta and eta are incorporated into the flux F when getFlux is called. This is always 3 variables. SpaceDim refers to only the derivatives that are meaningful in this bizzare application.

virtual void ResistivityOp::diagonalScale ( LevelData< FArrayBox > & a_rhs ) [inline, virtual]

Set the diagonal scaling of the operator. If you are solving rho(x) dphi/dt = L(phi), this would mean multiply by rho. In EB applications, even for constant coefficients, it means to multiply by kappa.

Implements TGAHelmOp< LevelData< FArrayBox > >.
