ABAQUS-滚石冲击铁丝网模拟

讲的不错，解决了我的问题，非常专业。只有一点不好：声音太小了，吐字不太清楚，有时候听不清说的啥。

您好 您这个网是二维正交的吗

请问我的梁单元材料属性设置了 怎么没断裂哦 damage设置的那几个参数需要满足啥吗

您这个是inp文件，请问有初始cae文件吗

滚石的质量在哪里设置呢，我怎么查询不到

请问球的解析刚体怎么设置啊

你好，请问这个算例里面有设置element deletion吗？我在学习做一个桁架结构的压缩模拟，也是用的梁单元，想模拟出压缩断裂的效果，材料参数我设置和这个里面一样，但是得不到这里面这种破坏的效果而是直接突出去一条很大的尖角，是怎么回事呢，劳烦大神指点一下。

参考点设置好了，但是现在运行结果出现了错误The rigid bodies with the reference nodes contained in node set ErrNodeRefNodeNoMass have no mass associated with them and some degrees of freedom of the reference node are not restrained. Either mass must be defined or all of the translational degrees of freedom must be constrained. See the status file for further details. The rigid bodies with the reference nodes contained in node set ErrNodeRefNodeNoRot1Axis have atleast one axis about which the rotary inertia magnitude is zero, and the rigid bodies have atleast one rotational degree of freedom which is unconstrained. Either rotary inertia must be defined at the reference nodes or all of the rotational degrees of freedom at the reference nodes must be constrained. See the status file for further details. Abaqus/Explicit Packager exited with an error - Please see the status file for possible error messages if the file exists. 请问是什么问题呢？

刚开始学，还不太会，直接按照视频里的教程画的，请问怎么建立参考点呢？

请问运行结果显示部分2缺少参考点是什么原因？怎么处理呢？麻烦了
