Abstract	A new automatic local remeshing method, based on changing the connectivity of meshes, is presented in this paper. When terminating computation in the Lagrangian framework is due to computational grids with large deformation problem, a remeshing phase in which a new grid is defined is introduced, with a remapping phase in which the Lagrangian solution is transferred (conservatively interpolated) onto the new grids. The new meshes after the remeshing phase is obtained so as to improve the mesh quality. If remeshing does not help improve the mesh, we present a new automatic local remeshing method, based on changing connectivity of the mesh, which to handle geometric intersection, and leads to general polygonal mesh. A series of numerical examples are presented to demonstrate the performance of our new method with the large deformation problems.
