Title: Mixed Finite Element Extensions of MAC Schemes Abstract: The Marker-and-Cell (MAC) discretization is a surprisingly efficient discretization for Stokes equations, converging at second order with a small number of degrees of freedom and sparse stencil. But that second order convergence can be explained by a cancellation of errors, which makes it fragile. Can we maintain second order convergence for MAC discretizations on deformed or non-conforming grids, or for creeping flows with anisotropic effective viscosities? We develop an approach for…
