摘要：
Finite elements for which an interpolation scheme is postulated on the boundary only are potentially more accurate. An efficient and easy technique for generating such elements from classical displacement element-types is presented. The method is applied to the Poisson problem using rectilinear triangles with quadratic interpolation. Suitable error measures are defined and convergence is discussed. A benchmark demonstrates the computational efficiency of the proposed method.
