Error Estimation of Weak Galerkin Finite Element Method for Solving Time-Dependent Brinkman Equation
摘要
Abstract
We solved time-dependent Brinkman equation by the weak Galerkin finite element method. Corresponding error equations and error estimates were established by using semi-discrete scheme only for the discrete space and full-discrete scheme for the time and space discretization.We obtained the optimal rate convergence in H1 and L2 norm for the velocity function,and in H1 norm for the pressure function.So that the weak Galerkin finite element method was applied more widely.关键词
