Title: | Superconvergence of Piecewise Linear Semi-Discretizations for Parabolic Equations with Nonuniform Triangulations | Authors: | Barbeiro, S. Ferreira, J. A. Brandts, J. |
Issue Date: | 2005 | Citation: | Journal of Mathematical Fluid Mechanics. 7:0 (2005) S192-S214 | Abstract: | In this paper we study the convergence properties of semi-discrete approximations for parabolic problems defined on two dimensional polygonal domains. These approximations are constructed using a nonstandard piecewise linear finite element method based on nonuniform triangulations of the domain and considering a variational formulation with a sesquilinear form which can be no strongly coercive. In order to increase accuracy a post-process procedure is studied. | URI: | https://hdl.handle.net/10316/7738 | DOI: | 10.1007/s00021-005-0153-y | Rights: | openAccess |
