非线性分析的问题(关系到毕业设计，急)

这个问题该如何解决呀？那位高手指点一二
*** WARNING *** CP = 114.406 TIME= 22:43:09
We switch to a force TOL = 1.0E-2 with REF VALUE = 1.0 to continue the
analysis. Please verify the analysis with this relaxed TOL. You may
need to re-specify NSUB or CONVTOL commands for convergence and
accuracy of solution.
*** ERROR *** CP = 154.938 TIME= 22:43:52
Solution not converged at time 5.6875E-03 (load step 1 substep 3).
Run terminated.
*** WARNING *** CP = 155.078 TIME= 22:43:55
The unconverged solution (identified as time 1 substep 999999) is
output for analysis debug purposes. Results should not be used for
any other purpose.
