“…In the literature, net structures have been modelled using truss, beam, cable or spring elements to represent the twines (Fredheim, 2005;Gignoux and Messier, 1999;Li et al, 2006;Huang et al, 2006;Zhan et al, 2006;Zhao et al, 2007), or using 2-D membrane elements (Lader and Fredheim, 2006;Tsukrov et al, 2003;Priour, 1999;Tronstad, 2000). The previous work included custom made software and/or elements, and focused on the hydrodynamics and displacements rather than the distribution of loads in the model.…”
