Numerical solution for subsurface reservoir simulation
… Nevertheless, in most of the cases, the exact solutions in the classical sense of those models are not available. The study of numerical approximation of PDEs is therefore an active research area and there is an extensive literature on numerical methods for PDEs. In this work, we review some …

The numerical solution of waveguide discontinuity problems
… Results are obtained by the simultaneous solution of matrix equations, generated by Fourier analysis, which relate the complex amplitudes of orthogonal electric and magnetic field components. In some cases the solution is found to be sensitive to the way in which infinite series of field …
