梁的曲率问题（求大神指点）

Ryoko_Curly

做的是一个圆柱加筋类的结构，蒙皮是壳，用梁做加强，受集中力作用
会产生较大的弯曲变形，梁也是，然后就是如下的错误，不是很理解，是梁法线定义的问题吗？

For 162 beam elements either the average curvature about the local 1-direction differs by more than 0.1 degrees per unit length as compared to the default curvature or the approximate integrated curvature for the entire beam differs by more than 5 degrees as compared to the approximate integrated default curvature. This may be due to a user-specified normal or due to the nodal averaging routine used by Abaqus. This difference may cause unexpected behavior of the beam and you may want to verify that the beam normals are correct for your problem. The elements have been identified in element set WarnBeamCurvature1.

自己顶一下！ 难道大家没遇见过这个问题？

还是没有人回复吗？ 继续顶 版主给解析一下可以吗
