Monotone finite volume schemes for diffusion equations on polygonal meshes
TLDR
We construct a nonlinear finite volume (FV) scheme for diffusion equation on star-shaped polygonal meshes and prove that the scheme is monotone, i.e., it preserves positivity of analytical solutions for strongly anisotropic and heterogeneous full tensor coefficients. Expand

Linearity preserving nine-point schemes for diffusion equation on distorted quadrilateral meshes
TLDR
We employ the so-called linearity preserving method, which requires that a difference scheme should be exact on linear solutions, to derive a nine-point difference scheme for the numerical solution of diffusion equation on the structured quadrilateral meshes. Expand
