Ansys Joint Probe results

[scarules2006]

Hello everybody!
Today, I've encountered something strange while I was analyzing a bush in Workbench 15. I've sliced my bush in Design Modeler in regular shaped geometries so I could get less and better elements while meshing and I've obtained some good results. After this, I've refined the mesh so I could see the direction where the results are headed. Surprise, surprise while the Mises stress and the strain were almost in the same spot, the joint probe got higher with an order of magnitude(the resulted force from my displacement). How can this be? What could have went wrong? The first results are according to reality, but I usually refine my mesh to investigate the results. Thank you!

I've managed to find an alternative solution to my problem. To avoid the case scenario that I've encountered, it's better to use, when you can, displacements instead of joints. When I've replaced the joints with radial and axial displacements, the force reactions were ok when I've refined my mesh. Hope this helps! Good luck!
