我在计算的时候总是出现 Exit number 3015
out文件里面有：


             Unable to reduce the time step below the minimum value
             allowed, and to still satisfy the user criteria in the AUTO
             STEP history definition option. Either change the criteria
             or reduce the minimum time step allowed.
             failure to converge to tolerance
             increment will be recycled
             increment cut-back number     2
             *** error - unable to reduce time step below minimum of    1.00000E-06
                         specified in input
*** error - can not figure out contact priority
请问各位大侠怎么解决啊？
