[交流] 有关workbench钢筋拉拔问题

想问一下有没有大佬用workbench做过有关钢筋拉拔的模拟，自己做了好多次有关这个方面的模拟，但是一直没计算成功，每次求解时一直出现错误或者警告，困扰自己很久，希望得到大佬们的帮助。部分错误与警告如下：
1. The solver engine was unable to converge on a solution for thenonlinear problem as constrained. Please see the Troubleshooting section of the Help System for more information.
2. The unconverged solution (identified as Substep 999999) is output for analysis debug purposes.Results at this time should not be used for any other purpose.
3. Element 401194 located in Body "Solid" (and maybe other elements) has become highly distorted. You may select the offending object and/or geometry via RMB on this warning in the Messages window. Excessive distortion of elements is usually a symptom indicating the need for corrective action elsewhere. Try incrementing the load more slowly (increase the number of substeps or decrease the time step size). You may need to improve your mesh to obtain elements with better aspect ratios. Also consider the behavior of materials, contact pairs, and/or constraint equations. If this message appears in the first iteration of first substep, be sure to perform element shape checking. Named Selections for the offending element can be created via the identify Element Violations property on the Solution lnformation Object.
