Abstract：

A method is introduced in the paper,which is based on the GREX graphic function of NDP\|FORTRAN,so the remeshing program can show whether the new grid is in conformity with the old grid on the screen.The new grid can be compared with the old grid,and the point for new grid may be modified to approach the boundary well.In addition,the method can realize the field variables transference successfully and effectively in remeshing for 2D finite element analysis.
