Hello,
I am trying to build a subroutine to swap out the Hertz contact force model with one of the more complex ones (e.g. Flores et. all). What I don't understand is how the c_impact function returns three force components when the gap and gapdot values are scalar.
While there is an online help on the impact function, I had not luck finding the statement of the impact force's components calculation.
Thanks,
Josef
