hello!!!

when I run COSMOSMotion, an error message appears suddenly.

here it is:

" --- Simule Assemblage2 en samedi 27 août 2011 01:45:19, Frames: 500, Temps: 3 ---

At time 1.520527116E-06 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.

I did everything in the rules of art: I have well defined materials,geometry (no interference), the Liasons / constraints, I have verifiedthat there is no conflicts between them ....... etc.

i dont understand reason of this message so!!!

a big thank you to those who help me.
