Can I obtain resultant contact normal force?

Question

I am simulating an internal gear pair with the same number of teeth in rotation. I defined a cylindrical coordinate system for the internal gear and would like to export resultant contact normal forces and direction in each contacting node of the internal gear.

For the moment what I get is Contact normal force in X, Y, Z global coordinates.

Can I extract the information desired directly from Marc or do I have to post-treat myself?

Thank yu very much for you help!

I think only Contact Normal Force X,Y,Z are in the t16 file. Contact Normal Force is calculated in Mentat from the components. You can easily do the same in your Python code.

There is another option in Mentat: you can plot Contact Normal Force and write Nodal Values to a report. You will then see Contact Normal Force in the rpt file.
