空间梁系不能求解
在ansys中建立了空间梁系模型，求解时说竖向位移超出程序允许范围，不知是什么原因，请各位帮忙看看？命令流如下：/prep7

solve 约束不充分，检查一下约束。 不是约束的问题，我曾试着将其改为悬臂梁，问题依旧，相关命令流见上文加注释的约束语句。 2.oe11,0写成O了吧，看看单位有没有问题，你有的是国际单位，长度应该用米，然后就是你各条线之间是否共享关键点还是共享节点，如果只是共享节点的话，要Merge下 非常感谢dzy0530兄的热情帮助，问题已解决，确实是由于弹模书写出错造成的。谢谢 原帖由 yanleeq1973 于 2008-6-23 08:59 发表 http://www.chinavib.com/forum/images/common/back.gif
