A Positivity-Preserving Finite Volume Scheme for Diffusion Equations on 2D and 3D Grids

论文摘要

<正>We propose a new positivity-preserving finite volume scheme for the anisotropic diffusion problems on general 2D and 3D meshes based on a new nonlinear two-point flux approximation.The scheme uses both cell-centered and cell-vertex unknowns.The cell-vertex unknowns are treated as auxiliary ones and are computed by two
