Symmetry Constraint Different Results

Uğur Kaya_22358

Hi,

 

I have quite a complex model, so I want to do a simulation with symmetry constraint. However, I wasn't sure about the constraint and I created two models. One of these is without symmetry constraint with whole model and the other one is with symmetry constraint by using slide constraint with half model.  But the results are different. Actually, it should be the same. Is this normal? or have I made a mistake?

 

Best regards

Adding a couple images would be helpful to understand what you're doing.

This is a nice overview.
