abaqus 计算中的问题

我的模型算通了，但总是不收敛，刚学习abaqus，不知道哪出了问题，错误如下：
***WARNING: THE STRAIN INCREMENT HAS EXCEEDED FIFTY TIMES THE STRAIN TO CAUSE
FIRST YIELD AT 153 POINTS
***WARNING: EXCESSIVE DISTORTION AT A TOTAL OF 929 INTEGRATION POINTS IN SOLID
(CONTINUUM) ELEMENTS
***NOTE: ELEMENTS ARE DISTORTING EXCESSIVELY. CONVERGENCE IS JUDGED UNLIKELY.
***NOTE: SEVERE CONTACT OVERCLOSURES EXIST. CONVERGENCE IS JUDGED UNLIKELY.
***ERROR: TIME INCREMENT REQUIRED IS LESS THAN THE MINIMUM SPECIFIED
请各位高手帮忙解答一下，小女子不胜感激。

***ERROR: TIME INCREMENT REQUIRED IS LESS THAN THE MINIMUM SPECIFIED这个出现的原因就是系统默认的计算次数是100即inc=100. 将inc改大些，就会解决
一般来说ABAQUS系统默认的INC足够不大的分析模型求解的了，出现以上错误，一般都是分析模型建立的有问题。尤其是涉及到接触对等行为的定义。
