| Abstract: | For the finite element adaptive refined and unrefined mesh in simulation of sheet metal forming,an algorithm to display physical quantity on a section based on adaptive mesh topology was proposed.This algorithm could fast and precisely obtain the intersect line between the specified section and the finite element adaptive mesh and then accomplish displaying relative elemental physical quantity on a section.The integration of this algorithm in the post-processing system of sheet metal forming simulation system FASTAMP shows that it is characterized of more rapid in searching,more precise and easier applied. |
