N2 - This paper describes an algorithm for automatic rezoning of the finite element mesh, which can be used in adaptivity techniques where the initial topology is conserved. Difficulties like the definition of an adequate mesh density, its continued interpolation and the description of curved boundaries have been overcome successfully. The algorithm has been used in some strain localization problems. The output of a first analysis with a coarse, constant density mesh is used as an indicator to control the mesh spacing in a subsequent calculation, leading to an improved solution. The improvement of the solution upon remeshing is shown.
