摘要:In this paper we study a weak Galerkin finite element method (WG-FEM) with second-order accuracy in time for solving one type of parabolic equations. We apply a discrete weak gradient operator on discontinuous piecewise polynomials in the numerical scheme. Fully-discrete WG finite element scheme is introduced and analyzed. Optimal order error estimates are derived in the L-2 norm. Numerical experiments are performed to verify the theoretical results. (C) 2018 Elsevier Ltd. All rights reserved.
