Abstract：

This paper takes the severe distortion of the finite element mesh and the discrepancies in the modeling as the remeshing criterion. The surface node information of the deformation is picked up. A new body is produced through the information. The body is decomposed into some parts which can mesh hexahedron element. The nodal point of the new mesh can be found in the element of old mesh according to the volume equality algorithm. The data transformation can be realized by the inverse isoparametric mapping in FEM based on analytical character. Remeshing for three-dimensional finite element in metal forming processes are realized.
