英文摘要：

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 pro- posed. 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.
