    create an output block selecting groups from the menu and select the interfaces from which you want the plots.

     

    once output block is created edit it and input DEF  in variable field which will provide all normal and tangential forces in X Y Z direction

    I have a question.

    What is the difference from the contact force in hyperview and in hypergraph?

    In hyperview we have the contact force in all points of a shell but in hyper graph 2D we only have one value.

    Is the value in hyper graph 2D the sum of all in hyperview?

    Thank you

    Hi,

    In HyperView the contact forces are extracted for the whole model whereas in HyperGraph we are separately extracting the contact forces from the interfaces defined.

    Hi

    So is it the sum of all stress x area in the interfaces?

    Hi,

    The relation for contact force depends on the magnitude of mass of the body and the sudden change in velocity of the body, which is acceleration. If the system of objects is not accelerating, then the contact force between the bodies is just the initial force. There are many open web resources available on calculating contact forces and I request you to go through those for better understanding of this concept.
