| Abstract: | Remeshing is one of the key factors to restrict finite element simulation. The criteria for judging remeshing or not remeshing and the technique of transfer of the fields from the old meshes to the new meshes are discussed in detail, and two methods for in or out test are presented. The transfer of three dimensional fields from the old meshes to the new meshes is processed successfully by using these two methods. The correctness and validity are verified by the example. |
