I'm facing a problem with my Abaqus model for a shwedler dome similar to the thread above.
Has anyone encountered this problem. if so, how did you relove it?
The Linear analysis runs without much trouvle but the Non linear analysis that follows on the same dome aborts in the middle.
The error message that abaqus shows after aborting the non linear analysis is as follows:

For 794 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 222 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.
