预应力网壳的动力分析不收敛 请达人指教 附命令流
上层是K8单层网壳 采用188单元 下部张弦体系 采用LINK10静力分析没问题 动力分析两三步后就不收敛了 请大家帮忙看下 共同学习

建议看一下王新敏老师的--ansys工程结构数值分析书--有很多网壳的例子我用过几次link10，建议对link10单元加一个很小很小的初应变比如1.0e-5以获得求解的稳定性和较好的收敛性，这个与只受拉不受压特点有关。可以多试几次不同的小初应变的数值。
r,2,agjx,1.0e-5

多谢LINK10本身就是非线性 好像挺麻烦的
我改了LINK8就是线性分析 就没这些问题了
我采用的是温度变化产生预拉力 利用实常数不知道能不能得到同样的效果 我再试试
