Direction of the prismatic joint is determined by r[2], which is a vector pointing from frame_a to frame_b.

Optionally, two additional one-dimensional mechanical flanges (flange flange_a represents the driving flange and flange support represents the bearing) can be enabled via parameter useFlange. The enabled flange_a flange can be driven with elements of the Modelica.Mechanics.Translational library.

In the "Initialization" block, elongation s of the joint, velocity of elongation v as well as acceleration of elongation a can be initialized.

It can be defined via parameter (in "Advanced" tab) stateSelect that the relative distance s and its derivative shall be definitely used as states by setting stateSelect = StateSelect.always.

In "Animation" group, animation parameters for this model can be set, where zPosition represents the model's position along the z axis in 3D animation. Some of the values can be preset by an outer PlanarWorld model.
