    Uneven displacement

    Brian Stranyak

      Any idea why I would have uneven displacement on a symmetrical part, in a two part assembly? The blue portion is a separate part. As I refine the mesh it becomes more red (same scale). Just wondering. The stress seems to be more even albeit blotchy. Thanks in advance

          Most likely from your mesh being entirely too coarse. You probably have a situation where you aren't really representing a circle well because there aren't enough elements. Your stress results being blotchy indicate that as well. Put in a much finer mesh and rerun it and see what happens. If you choose a value that is the diameter/some integer for the mesh size, you are much more likely to get a mesh that is symmetrical. Also, use the curvature based mesher if you used the standard mesher.
