Hexahedral elements are computationally efficient for three-dimensional modelling of metal forming processes but its utilization is still below expectations due to significant barriers caused by remeshing. Remeshing of hexahedral meshes is generally

Many finite element programs currently utilised in the three-dimensional simulation of bulk metal forming processes make use exclusively of tetrahedral shaped elements because of the advantages of such elements in meshing and remeshing operations. Th
