回复: 【讨论】ansys中的接触与ansysy/ls_dyna中的接触碰撞的区别
contact in ansys was based the penalty method, Lagrangian method and tha Augumented lagrangian method. the construct the contact element between the contact faces with a powerful wizard. while in Ls-dyna, the contact is established based on the explict method , it calculate nodes' acceleration directly, and do not need to define the contact element. for the crash problem i reccommend you use LS-dyna, it will be much convenient. |
