Abstract FE-simulation of complex metal forming processes is often hampered by mesh distortion. In this case a new mesh of quadrilateral of hexahedral elements must be generated (remeshing). This cannot be done effectively by using currently available methods. This paper presents a new algorithm for the generation of hexahedral element meshes. The quality of the algorithm is demonstrated by the simulation os a complex forging process.
