baqus计算报错总结
原因及解决方案
原因：(1)没有单元赋予正确的property。
(2)单元类型不对。
在abaqus中查找ErrElemMissingSection，
并修改成正确的属性或类型。
给所创建的梁单元赋材料
通常是胶的一维单元和实体单元没有分开造成的。可
以在abaqus中查看：ErrElemVolSmallNegZero。
把施加重力加速度的单元集中刚性连接处的单元去除
掉
原因：所创建的connector截面没有赋予坐标系
原因：没有将hinge单元转到坐标系下
解决方案：
单元类型设置为了刚体类型R3D4或R3D3
消除自由边
将焊点的component赋予给elset。
梁单元轴的切线方向和梁横截面第一个轴的方向几乎
是平行的，不符合定义梁横截面方位的要求。
