The explicit finite element method ( fem ) based on the varying time - step was selected to analyse the dynamic roll - pass process ; the nodes on the leading face of the steady - state elements set was extracted and projected onto a plane to give the required mesh, also called the origin mesh ; the implicit fem was selected to analyses the inter - pass transient thermal process ; a geometric part from the mesh was generated and meshed by using the quadrilateral elements, a heat transfer analysis was selected to transfer the node temperature data ; a new model was created by using hexahedral elements, mapping the node temperature and the equivalent plastic strain on the integration points
