ansys ls-dyna shell163加转速或转矩后体积膨胀，不旋转只膨胀

wugx

ansys ls-dyna shell加转速（OMGX）或转矩后体积膨胀，不旋转只膨胀，求大神解惑，我的模型是个车轮，原本定义的单元类型是solid164，结果都说其 没有转动自由度，于是换成了shell163，重新划分网格，好几次了，都是上面这种情况，我的体是由一个面绕轴旋转而成，然后按面划分的网格，最后创建了part和component，而component是选的节点，生成的也是节点，最后定义了时间、转速数组，将转速加载到了刚定义的component上，不知那个地方出了问题？？？

这是两个转动的例子，或许对你有帮助
