请教Midas Civil弯梁的建模问题

我建了一个弯梁的模型，两端节点采用双支座模拟，从节点都定义了局部坐标。运行之后，信息窗口中显示了以下信息：

MULTI-FRONTAL SOLVERAVAILABLE MEMORY =    1.4 GBYTES

很郁闷，不知道哪里出了问题。我把模型发上来，请各位指点迷津，赐教一下弯梁的建模技巧。
谢谢大家！

边界条件的问题吧，全部固结是计算不了的

不是全部固结的，没有约束弯矩。

支座的三个方向都是1是不是有问题，不能这样做的吧。

tenten1 发表于 2019-5-2 11:37:52

是定义了施工阶段之后出现的错误吗？

边界条件问题吧。。三方面固定不行哦
