我做MIDAS/CIVIL分析时，显示涵数不正确，不知哪位仁兄遇到过没，如何解决

回复 主题 mufan 的帖子

你的问题应该是你的约束有问题，请再检查你的约束条件。
PS：以后建议还是能把模型上传而不是把这些贴出来，或许能更容易的让大家帮助你。

请高手指教，附件mct文件

上面模型基本解决了，还有一模型，请高手指教

我的版本是6.71的，但是打不开你的模型，应该是版本不兼容。记得是MIDAS的6.7以前版本相互间不能打开的，只能导出*.mct文件后再来修改命令才可以，很麻烦的。我看还是你自己再看看帮助或是找例题去解决吧。
我也只是刚学MIDAS不久，可能是我是在做实际项目，比较好找问题吧。建议去看看教程类的，应该有帮助。

谢谢，我想可能是破解版的，不稳定的缘故罢了，后来我在正版6.1.1上建模就可以了
