2008 journal article

A high order compact MAC finite difference scheme for the Stokes equations: Augmented variable approach

Journal of Computational Physics, 227(17), 8177–8190.

By: K. Ito n & Z. Qiao n

author keywords: Stokes equations; compact fourth order MAC finite difference scheme; staggered grid
TL;DR: A high order compact MAC finite difference scheme based on the staggered grid is developed for solving Stokes equations with a Dirichlet boundary condition on the velocity through a novel high order boundary treatment via introducing a suitable augmented variable. (via Semantic Scholar)
