OSTI ID:658345
The authors construct reliable finite difference methods for approximating the solutions Maxwell`s equations and equations of magnetic field diffusion using discrete analogs of differential operators that satisfy the identities and theorems of vector and tensor calculus in discrete form. These methods mimic many fundamental properties of the underlying physical problem including the conservation laws, the symmetries in the solution, the nondivergence of particular vector fields and they do not have spurious modes. The constructed method can be applied in case of strongly discontinuous properties of the media for nonorthogonal and nonsmooth computational grids.
