Detailed Description

Base class for making Robin domain boundary conditions with MFHelmholtzOp.

Robin bcs are in the form A*phi + B*dphi/dn = C. We impose dphi/dn = (C - A*phi)/B where phi is extrapolated to the EB to first order.

Note

The B-coefficient is not the same as in the Helmholtz equation...

In our notation, n points into the computational domain.
