Convergence problem in ANSYS Workbench

[Elementalnature]

Hi, i solved a model but i got an error saying that "The solver engine was unable to converge on a solution for the non linear problem as constrained". Can someone offer advice on how i can fix this error?

It sounds like you have not adequately constrained the problem. You need to avoid uncontrolled rigid body motion as much as possible. If some rotation or linear is required, you need to constrain it somehow, possibly using contact sets. Is this some type of chuck on a roll handling equipment?
