四边形上新的H（div）协调Darcy-Stokes元（英文）

发布时间：2021-05-08 12:18

　　This work develops a new mixed finite element method for arbitrary convex quadrilateral meshes to solve the Darcy-Stokes problem.We propose an H（div）-conforming element which based on a spline element over the crisscross subdivision of a quadrilateral to approximate the velocity.And the pressure is approximated by piecewise constant.Then we give the convergence analysis of our element and construct a new discrete de Rham complex.Moreover,an explicit local basis representation is provided.Lastly,...
