Dear all

I simulated the beam with ansys5.6, but the following error message appeared:

DOF(e.g. Displacement)limit exceeded at time 1( load step1
substep 1 equilibrium iteration 1)
Maximum value=371934510 Limit=1000000.
My be due to an unrestrained or unstable model.


Please tell me the possible reasons if you know about it.

Thanks,

Zhu Xiaorui
