Contact - Imapct

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

Thanks! However it still seems strange to me that the area is used as input to the cnfsub but not used within it. Is it possible that it is just one of the unused values of the function (like the gapdotdot input for example)?
