我也很疑惑,ansys模型是我的同事弄的,我用abaqus算和她对比,模型单元数差不多
就算ansys模型少1万左右,差距也这么大吗
另外再问一个问题:帮助文件里说,The iterative solver can be used for models that have a relatively small number of constraint equations (such as multi-point constraints, surface-based tie constraints, kinematic couplings, etc.). While linear constraints that arise from modeling techniques such as equations, kinematic couplings, and MPCs are allowed, dense constraints that eliminate many (i.e., thousands of) slave equations per master equation will generally lead to convergence problems and may even cause the iterative solver to fail.
我的模型里有mpc beam约束,是不是就不能用迭代解法? |
