Enriched multi-point flux approximation for general grids

QY Chen, J Wan, Y Yang, RT Mifflin - Journal of Computational Physics, 2008 - Elsevier
It is well known that the two-point flux approximation, a numerical scheme used in most
commercial reservoir simulators, has O (1) error when grids are not K-orthogonal. In the last …
