“…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.…”

Abstract.A piece of netting, consists of the 8 8 meshes, fixed on a square frame, was simulated and the tensions and their distribution, the positions of knots and netting shape were calculated by means of MATLAB in computer. The dynamic mathematic model was developed based on lumped mass method, the netting was treated as spring-mass system, the Runge-Kutta fifth-order and sixth-order method was used to solve the differential equations for every step, then the displacement and tension of each mass point were obtained. For verify this model, the tests have been carried out in a flume tank. The results of the numerical simulation fully agreed with the experiments.

“…Finally, the configuration of the net in current can be simulated. The calculation method for the model has been explained fully in our previous studies [16][17]. Here only a brief outline is described.…”
