HELP! Iteration repeting itself

HELP! Iteration repeting itself

HELP! Iteration repeting itself

(OP)
Hello all,

I'm trying to simulate an ejected molded component. I used helius to map the material and used the automatic stabilization to keep eliminate the rigid body movement. First, i tried with a linear material and everything was fine.
Then i mapped the experimental data, and run the analysis. It did some increaments just fine, but then this happens:

UMBER OF EQUATIONS = 2416665 NUMBER OF FLOATING PT. OPERATIONS = 7.50E+12

CHECK POINT START OF SOLVER

CHECK POINT END OF SOLVER

ELAPSED USER TIME (SEC) = 236.90
ELAPSED SYSTEM TIME (SEC) = 0.80000
ELAPSED TOTAL CPU TIME (SEC) = 237.70
ELAPSED WALLCLOCK TIME (SEC) = 238

CONVERGENCE CHECKS FOR EQUILIBRIUM ITERATION 49


AVERAGE FORCE 2.81 TIME AVG. FORCE 2.92
LARGEST RESIDUAL FORCE 3.275E-02 AT NODE 402492 DOF 2
INSTANCE: JDEUS-1
LARGEST INCREMENT OF DISP. 6.949E-02 AT NODE 220176 DOF 3
INSTANCE: JDEUS-1
LARGEST CORRECTION TO DISP. -3.918E-06 AT NODE 402492 DOF 2
INSTANCE: JDEUS-1
FORCE EQUILIBRIUM NOT ACHIEVED WITHIN TOLERANCE.

As you can see, the iteration repeats itself during 40 increaments. It should already have achieved equilibrim: 0.005*2.81*2.92 > -3.507e-02.

Can someone help me?
Thanks

Hi jaulino

Did you use implicit method?
I got the same problem when I used implicit method. If someone can help I will appreciate for him.
