Abstract: In this paper, we present a method to accelerate incremental bulk metal-forming simulations by using different mesh discretisations in two depending meshes. This multimesh method is preventing a loss of local resolution by using a special data transfer. Two example processes show the working of this method and the archieved acceleration.
