我想做一个简单的运动，就是一个物块先平动10秒，再绕质心转动10秒，弄了一个简单的脚本，可是仿真时平动完后就错误了，大神们知道哪里错了吗？
这是提示的错误：
WARNING: The distance between the J marker and the I marker is 500.0.
(No warnings if less than +/-1.0E-003)
Revolute Joint = .MODEL_1.JOINT_2
I Marker = .MODEL_1.PART_2.MARKER_5
J Marker = .MODEL_1.ground.MARKER_6
WARNING: The markers for MODEL_1.JOINT_2 are not initially coincident.
The relative displacement between the markers, expressed in the
J marker coordinate frame is:
Delta X = -500.0000 Delta Y = 0.0000 Delta Z = 0.0000.

WARNING: MODEL_1.JOINT_1 is already activated. Activation ignored.
WARNING: MODEL_1.MOTION_1 is already activated. Activation ignored.
WARNING: The data set is kinematically determinate. However, a dynamic analysis
has been requested. A kinematic analysis with the SIMULATE/KINEMATICS
command would be more efficient and possibly more accurate for some of
the computed quantities.
As requested, the simulation will continue with a dynamic analysis.

ERROR: At time 1.000000000E+01 the integrator is unable to start/restart. 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.
ERROR: Simulation failure detected.
ERROR: Simulation failure detected.
