请教 该如何施加哑元

我做了一个空心橡胶球做挤压试验 并且用auto/flex模块自动划分了网格 我做了一个与橡胶球同样大小的空心球做哑元 并用铰接副固结在橡胶球上 仿真无法进行 并有提示

The greatest error in an equation is 1.93993E+07 in the
   equation for FLEX_BODY model3.Flexible_Body_1 .
  
   The greatest change in a variable is 4.4109 in the
   variable for FLEX_BODY model3.Flexible_Body_1 .
  
   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
           EQUILIBRIUM, IC, KINEMATICS, or INTEGRATOR command to
           PATTERN = T.
       3.  Temporarily increase the value of the ERROR argument on the
           EQUILIBRIUM, IC, KINEMATICS, or INTEGRATOR command at
           time = 1.46681E-02 .
       4.  If one or more forces change rapidly or sharply near
           time = 1.46681E-02, modify the force or forces.
到底该如何用什么样的哑元，并采用什么方式才能与弹性体相连
