Abstract

In this paper, a hierarchical cylinders method is proposed to resolve penetration of yarns. The performance of the hierarchical cylinders method is accelerated by applying a spatial subdivision algorithm. The spatial subdivision algorithm refines the detected regions according to the properties of weft knitted fabric, which greatly reduce the calculation of collision detection. Based on the cuboid particle system, penalty contact forces act on the yarns with problematic penetration. Experimental results demonstrate that the proposed algorithm and method are efficient for weft knitted fabric simulation.
