ABAQUS的隨機振動，總會出現(xiàn)關(guān)于曲率的警告？

利用ABAQUS的顯示動力，我做一個U形管的激振模擬，總是出現(xiàn)這個警告，有哪位大神能指點一下，是什么原因嗎？
For 730 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.
請問是模型原因嗎
beam的local 1-direction就是梁的軸線方向，也即是normal方向，在梁的normal方向定義那里檢查一下是否正確的定義了軸線方向。property模塊。
