[求助] 急！求助ANSYS/LS-DYNA高手，计算总是出错out-of-range velocities

slave surface of interface =       1
      type                      =       14
      surface timestep          = 6.422E-04
      controlling slave node ID =       2
      part ID of slave node       =       1
      current minimum time step = 6.422E-04

      master surface of interface  =       1
      type                      =       14
      surface timestep          = 8.102E-04
      controlling master node ID =    18731
      part ID of master node    =       2
      current minimum time step = 6.422E-04

The LS-DYNA time step size should not exceed    6.422E-04
to avoid contact instabilities.  If the step size is
bigger then scale the penalty of the offending surface.

最近在做深孔钻削，先尝试只用一个细长圆柱打孔，计算时总是出现如上错误，试了很多办法均不能解决，希望大家能帮帮我，先谢谢你们了！
