本文在四面体网格上建立了扩散方程的一个单调的中心有限体积格式,它处理张量扩散系数和强间断扩散系数。这里的第一个新奇之处是提出
A monotone cell-centered finite volume scheme for diffusion equations on tetrahedral meshes is established in this paper, which deals with tensor diffusion coefficients and strong discontinuous diffusion coefficients. The first novelty here is to propose
