Force and torque change with displacement

Please login with a confirmed email address before reporting spam

What I want to achieve in a simulation (multibody dynamics) is to apply a certain external force and torque to an object, where the magnitude of the applied external force and torque varies continuously with displacement. Specifically, when the change in displacement is less than 1 [mm], I want the displacement value to 'revert' or 'hold' at the last achieved value that meets the conditions (for example, the last whole millimeter point). In other words, I want the forces and torques I apply to exactly result in a 1 [mm] change in displacement. I have tried many different settings, but nothing has worked, so I would like to know how to configure it properly.
