Hello Everyone

I am having an issue with a simulation that im working on and am looking for some help.

I have a flat cylindrical plate with a hole in the middle and two symetrical "bumps" on one face near the center. i then have a part that pilots in the center of the cylindrical plate and has a face that comes in contact with the two "bumps". i then apply a force pulling the part into the "bumps". Unfortunately the results that I am getting do not come out symetrical.I can rotate the relationship between the two parts as little as .1 degrees and the asymmetry will flip. I will provide a photo of this soon. Any and all help would be appreciated.

Thank You

Kevin
