Mimetic finite difference methods for diffusion equations on non-orthogonal non-conformal meshes
Mimetic discretizations based on the support-operators methodology are derived for non-orthogonal locally refined quadrilateral meshes. The second-order convergence rate on non-smooth meshes is verified with numerical examples. (C) 2004 Elsevier Inc. All rights reserved.
