摘要內容:
Abstract. We introduce a flux recovery scheme for the computed solution of a quadratic immersed finite element method. In the case of piecewise constant diffusion coefficient, we show that the end nodes are superconvergence points for both the primary variable p and its flux u. Furthermore, in the case of piecewise constant diffusion coefficient without the absorption term the errors at end nodes and interface point in the approximation of u and p are zero. In the general case, flux error at end nodes and interface point is third order.  相關檔案:poster.pdf
