Rectangle

Contactable rectangle

 Description The Rectangle element models a contactable rectangle. The contactable surfaces are the top and bottom of the rectangle. The thickness of the rectangle is used as the uncompressed length, ${L}_{0}$, in the contact force computation (for details, see Multibody Contact Modes).
