Reply To: Cross-coupled stiffness elements in LS-DYNA

Thank you for the documents! 

It seems that the preferred way to model bearing stiffness is by the use of joints with rigid bodies. However, I can only see input options for the diagonal stiffnesses (x-force as function of x, y-force as function of y), but no possibility for cross-coupling (x-force as function of y, etc). I might have to resort to either the DMIG-option or simply program forces by the use of the *DEFINE_FUNCTION-option, which would be valid for transient simulations.

However, the files give a lot of valuable information about the best practices for modeling rotating systems with contact, which I am very grateful for! Thank you.
