平顺性仿真时，出现如下错误，盼指点

shuiyixian

我的车是四轴半挂车，在做平顺性仿真时出现如下错误，说明一下，我的牵引车单独仿真时是可行的，加上挂车后就报错，.提示bgs_fifth_wheel_to_trailer.field .错误，有没有人知道可能会是什么引起的这种错误，求指点！万分感谢！

   Try the following in this order:
       1.  Use the MAXIT argument on the EQUILIBRIUM, IC, KINEMATICS,
           or INTEGRATOR command to increase the maximum number of
           iterations.
       2.  Temporarily change the value of the PATTERN argument on the

       3.  Temporarily increase the value of the ERROR argument on the
           EQUILIBRIUM, IC, KINEMATICS, or INTEGRATOR command at

       4.  If one or more forces change rapidly or sharply near
