Finding nodal reactions normal to a curve

Pioneer

I currently have a solid model with a cylindrical hole through the middle (to hold a pin) and tabs and a slot to allow for a pinch bolt.  I have a rigid element in the center of the cylindrical hole to simulate the pin, and forces applying compression to the tabs to simulate the pinch bolt.

 

I need to find the average normal force applied from the cylinder wall to the pin (or vice versa) to see how much frictional force the joint generates.  I used the free body feature in the postprocessing toolbox to show the forces, but my options are to show the component forces or the resultant forces.  Is there any way to show specifically the forces normal to the cylinder wall at each node?

 

Thank you,

Patrick

Patrick,

Did you try setting up a cylindical coordinate system?  If you do that and change the coordinate system in the freebody tool to the cylindrical coordinate system you create the component forces in the radius direction should be normal to the cylinder wall.

That did the trick, thank you.
