[求助] 在ABAQUS中提交job出现梁单元截面方向重合在一点的错误提示，求各位前辈指点已有1人参与

具体错误提示如下：Error in defining or computing beam section normal in 26 elements. The elements have been identified in element set ErrElemBeamSecNormal.
The beam cross-section direction vectors coincide at a node in 26 elements. The elements have been identified in element set ErrElemBeamSecDirVect.
Analysis Input File Processor exited with an error.
警告部分如下：MPCS (EXTERNAL or INTERNAL, including those generated from rigid body definitions), KINEMATIC COUPLINGS, AND/OR EQUATIONS WILL ACTIVATE ADDITIONAL DEGREES OF FREEDOM

Output request s is not available for element type mass

2 elements are distorted. Either the isoparametric angles are out of the suggested limits or the triangular or tetrahedral quality measure is bad. The elements have been identified in element set WarnElemDistorted.

For 18 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.

For 2 beam elements either the average curvature about the beam tangent 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 j_WarnBeamTwist.
