Force and torque change with conditions

Please login with a confirmed email address before reporting spam

One type of simulation (multibody dynamics) I want to achieve is to apply a certain external force and torque on an object, with the requirement that the magnitude of the applied external force and torque changes continuously with displacement. It should be such that the magnitude of the force and torque is just enough to cause displacement. How should I set this up?

Hi,

sounds like an optimization Problem. 1st I would measure the displacement w. 2nd vary the force and torque until your displacement starts to change.

The variation you can do via a parameter sweep with fixed steps or,

use parameter optimization of an optimization study.
