We devise and analyze vertex-based, Péclet-robust, lowest-order schemes for advection- diffusion equations that support polyhedral meshes. The schemes are formulated using …
M Gerritsma, A Palha, V Jain, Y Zhang - … Methods for PDEs: State of the …, 2018 - Springer
This chapter addresses the topological structure of steady, anisotropic, inhomogeneous diffusion problems. Differential operators are represented by sparse incidence matrices …

We present a discretization for Darcy's problem using the recently developed Mimetic Spectral Element Method (Kreeft et al.(2011) Mimetic framework on curvilinear …
In this work, a geometric discretization of the Navier-Stokes equations is sought by treating momentum as a covector-valued volume-form. The novelty of this approach is that we treat …
Abstract Structure-conserving numerical methods that aim at preserving certain structures of the PDEs at the discrete level have been an interesting research topic for many decades …
