Detailed Description

operator L is defined as L(B) = alpha B + beta*(divF) where F = eta((grad B - grad B^T) + 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.

Sets the scaling constants in the Helmholtz equation.

Parameters
a_alphaThe scaling constant that multiplies the identity term.
a_betaThe scaling constant that multiplies the derivative term.

virtual void ResistivityOp::diagonalScale ( LevelData< FArrayBox > &  a_rhs,

Scales the right hand side of the Helmholtz equation by the identity term in the operator. If you are solving rho(x) dphi/dt = L(phi), this means multiply by rho (or kappa * rho in embedded boundary calculations.

Parameters

a_kappaWeightedIf set to true, a_rhs will be scaled by the volume fraction in addition to the identity term.

Reimplemented from TGAHelmOp< LevelData< FArrayBox > >.
