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.
