User functions
===============

The user functions set the specific behavior of your multibody system. This behavior
is controlled by several actions for instance:

* Introducing the torque/force due to an actuator, see :py:func:`user_JointForces`;
* Imposing the trajectory of a specific joint (regardless the force required), see :py:func:`user_DrivenJoints` ;
* Creating a constraints between joints (i.e. gears), see :py:func:`user_cons_hJ` ;
* ...

The complete list of user functions is available below.
