大体积零件仿真出错。。。为什么呢？

小六汤包

两根重叠的杆（直径：20mm，长度：2.0E+006mm，质量：1.9606051433E+004），质点处设置了移动副和相应的驱动，为什么仿真无法进行呢？
系统提示：ERROR:   At time  0.000000000E+00 the integrator is unable to proceed.  Possible Causes:
(1) The accuracy required for the numerical solution can not be attained.
Relax (increase) the value of the acceptable integration ERROR.
(2) Incompatible redundant constraints, a lock up, or a bifurcation
situation.  The latter two indicate a mechanism design problem.
(3) The system includes a zero (or relatively small) mass on a part with
an unconstrained translational degree of freedom.
Make sure you have mass on all parts with translational degrees of freedom.
(4) The system includes a zero (or relatively small) inertia on a part
with an unconstrained rotational degree of freedom.
Make sure you have inertias on all parts with rotational degrees of freedom.
(5) An Adams element has a function expression that equals exactly itself.
For example,
     SFORCE/id1,I=id2,J=id3,ROT,FUNC=SFORCE(id1,jflag,comp,rm),and
     DIFF/id4,IMPLICIT,IC=0,FUNC=DIF1(id4).
Similarly,
     VARIABLE/id5, FUNC=VARVAL(id5)*TIME
equals itself at 1 second. Avoid setting an Adams element equal to itself.
