Abstract
Large strains in finite element simulations of metal forming require several remeshing procedures during the computation to take place. These remeshings should be performed automatically both for saving computational time and convenience. Such a remeshing algorithm has been well established for 2- dimensional applications and was recently presented for the 3-dimensional case.

A special feature added to the remeshing algorithm in both 2D and 3D is the refinement which offers the possibility to use a finer grid in certain areas of the finite element mesh. The remeshing/refinement algorithm can play an important role in the simulation of microstructure.
