110 Iteration Max

110 Iteration Max

110 Iteration Max

(OP)
I have a pretty complex nonlinear, static structural problem that I have simplified about as much as I can, before I start potentially affecting the validity of my results.  After running 110 iterations in WB V.11, the solver just stopped.  Based on the Force Convergence plot, it looks like the problem was going to converge after perhaps another 10-20 iterations.  I'm assuming that the 110 iterations is a default maximum.  Can anyone tell me where to change that value, if it can be changed?

Thanks

RE: 110 Iteration Max

Best thing to do would be to insert commands and issue:

NEQIT,130 ! allows for 130 equilibrium iterations

That's really quite a few iterations though.  I would suggest issuing the following:

AUTOTS,ON   ! Ansys determines time stepping scheme
SOLC,ON     ! Solution control on is a must for your case

Good luck,
-Brian

Thanks for the tip!  I'll give it a try.
