Static equilibrium

Hamed Hani
Hello Adams Community,
 
I am using Adams MaxFlex to run a nonlinear simulation.
 
I am generating the bulk data file in my code and importing the resulting `BDF` file into my model.
 
My model runs perfectly fine when I use a coarse mesh size like this image(the diameter of the circle is 4 cm):
5
But, as soon as I try a finer mesh size (dividing by 2) like this image, I get static equilibrium simulation convergence error(I don't change anything else about the model).
10
I tried to tweak the solver settings as it is suggested in this article:
 
 
I tightened and loosened the limits on translations (TLIMIT) and rotations (ALIMIT) while I relaxed the error, but had no success getting the simulation to converge. I increased the MAXIT value for convergence, but still no success.
 
Does anyone have any idea what might cause this problem?

    Hi Martin,
    Thanks for the answer!
     
    I tried so many combination of error, stability, and imbalance and I could not reach equilibrium at all. What I ended up doing was to run a 0.5 second simulation of the model without the flexible part to reach equilibrium. Then, I copied the resulting model and added the flexible part. I successfully ran the whole simulation (with the flexible part) without any equilibrium issues with this method.
