扭转梁后悬架 Roll & Vertical Force Analysis 出错

扭转梁后悬架 Roll & Vertical Force Analysis 出错
各位，我现在在做一个扭转梁后悬的k&c仿真，每一种仿真都很好（平行轮跳，反向轮跳，侧向力，纵向力，回正力矩），除了 Roll & Vertical Force 分析，
报错如下：

TVFLEXEFAULT_C
   A default *non-zero* damping is used for FLEX_BODY/1 (baocuo_roll_angle.zp11_rear_2005_fbs_Hframe1).
   By omitting specifying a damping ratio for FLEX_BODY/1 (baocuo_roll_angle.zp11_rear_2005_fbs_Hframe1)
   you have selected default damping characteristics for the body.
   The default damping is nonzero, as follows:
  
        1% for modes with natural frequency below 100Hz
       10% for modes with natural frequency between 100Hz and 1kHz
      100% for modes with natural frequency above 1kHz
  
   where the damping values denote a percentage of critical damping
   for a given mode.  This may be overridden in one of two ways.
  
      a) by specifying a function expression for CRATIO.  To remove
         damping altogether, set CRATIO = 0.
      b) by specifying CRATIO = USER(...) and supply a DMPSUB
         user written subroutine.
