How to change contact stiffness

      I'm working on a modal analysis simulation of a model. As I do this I get the following warning:


      The maximum contact stiffness is too big. This may affect the accuracy of the results. You may need to scale the force unit in the model.


      How do I scale the force unit in the model or change the contact stiffness?

      Try changing units to something smaller and see if that helps. For modal analysis, this warning should not be much of concern as the all contacts are treated as linear at their starting position.
