ANSYS Classic simple analysis - problem
ANSYS Classic simple analysis - problem
(OP)
Hello,
I have simple plane analysis with contact, but ANSYS can't solve it. Load must be a Force.
During solution occurs an error:
ERROR
There is at least 1 small equation pivot term (e.g., at the UY degree of freedom of node 252). Please check for an insuficiently constrained model.
Could you help me?
Thank you very much.
DB file is attached.

In Abaqus it's very simply but in Ansys it doesn't work.
Thanks.

There may several reasons for this, unconstrained/underconstrained model, you're applying rotations to element which do not have rotational degrees of freedom or you have large stiffness differences between adjacent elements etc. Please read chapter 15.8 in the manual before asking any more questions.
