Restudy on the Adaptive Mesh Technique for Seepage Problems

摘要：

　　The adaptive mesh technique to steady seepage with a free surface has been restudied using Trefftz finite element method (FEM).This approach reduces theeffects of mesh distortion on the results based on the conventional FEM.Numerical example has shown that Treffiz FEM may guarantee the rapid convergence during successive modifications of the initial mesh configuration.
