NX10 - Unexpected direction of deformation

Hi!

I'm experiencing some problems with the results of a contact simulation. When showing deformation magnitude in the graphics window one of the parts appear to be moving in the wrong direction. I have no clue of why this is happening.I am relatively new to these types of simulations so all help is useful Smiley Happy

The upper part moves upwards even though the force is applied downwards.Capture1.JPG

What solution sequence is this? SOL 101 is a linear solver with a small displacement/sliding assumption. Contact pairing is not updated and so this soler is not valid for finite sliding type problems.

 

Another potential issue is the deformatin scale in post. Contact problems, particularly those with initial gaps or penetrations, should always be post processed with the deformation scale set to 1 x Absolute. The 10% viewport scale factor can make contact deformations look strange.

I figured out what the problem was. I had to set initial deformations to zero, since some elements were overlapping.
Thanks anyways!
