Contact normal force

Hello,

I used the Cnfsub to print out the contact normal force and noticed that the force estimated by the impact function doesn't directly translate to the force components inside Adams. How does Adams calculate the contact force components? Are the direction vectors and area of contact used in the estimation?

Thanks,

Josef K.

I am not sure about all the specifics behind this, but one thing could be that you have multiple contact points between your contact geometries, and the cnfsub is called for each contact point.

In general the standard contact should be using the impact function to calculate the contact force.
