density of arrows in contact forces can't be controlled

Please login with a confirmed email address before reporting spam

When there's contact in solid mechanics simulation, there's an automatic node "contact forces" in results. There are Contact 1, Pressure and Contact 1, Friction Force nodes under this node. The density of the arrows (pressure and friction) under these two nodes can't be controlled, as when clicking "uniform" in arrow positioning, no arrow is plotted. Gauss points is the only option but the downside of doing so is that the arrows are too dense if the mesh is fine. How to overcome?

The contact forces are shown using a standard Arrow Surface plot. So it has all possible settings for controlling arrow placement and density.

thanks but as the attached picture, it looks different from an arrow surface plot

Dr Christensen thanks so much! Can any forum admin help? There must be a bug with uploading pictures. It used to work!
