Notes:
Due to more complex and severe design restrictions, more effective and faster finiteelement analyses are demanded. There are several ways to compute FE analysis efficiently: parallelcomputing, fast iterative or direct solvers, adaptive analysis and so on. One of the most effectiveanalysis ways is the combination of adaptive analysis and multigrid iterative solver, because anadaptive analysis requires several meshes with difference resolutions and multigrid solver utilizessuch meshes to accelerate its computation. However, convergence of multigrid solver is largelyaffected by initial shape of each element. An effective mesh improvement method is proposed here. Itis the combination of mesh coarsening and refinement. A good mesh can be obtained by the method tobe applied to an initial mesh, and better convergence is achieved by the improved initial mesh
