... dimensions. If the results in one dimension establish a new state of the art, improvements are expected for the two dimensional cases. We believe that they are related to the same issues encountered in one dimension and are related to the existence of sharp discontinuities inherent to this class...

.... However, in order to be efficient, it is still beneficial to choose the table dimensions discretization wisely. In our implementation, we use non-uniform discretization of table's dimensions. For, example the gas-oil-ratio (GOR) dimension is discretized using logarithmic grid, where a larger amount...

... for the saturation equation of two-phase flow in porous media in two space dimensions. The keys to high order accuracy are to use WENO reconstruction in space (which handles shocks and steep fronts) combined with a two-stage Radau-IIA Runge-Kutta time integrator. The saturation is approximated by its averages over...

... the dimensions of the fracture. By using no-flow boundary conditions on the exterior of the fracture domain, and allowing only a single cell in the direction normal to the fracture plane, our approach shares many of the basic properties of a lower dimensional representation. By maintaining the dimensionality...

The interpolation to grid nodes naturally uses a three dimensional linear function, with four undetermined coefficients instead of three. This requires at least four neighbouring cell centre values...
