Abstract：

To solve the mesh distortion in metal forming simulation,a local remeshing technique was presented. The calculation of element shape was used to determine when to remesh and specify the distorted element, and the characteristic of element boundaries was used to fetch contour of remeshing areas. After rezoning the remeshing areas, remapping algorithms was used to remap physical variables. ANSYS software and the secondary development tools APDL of ANSYS were used for the realization of this method. This method was proved by the simulation of punch process.
