Infinite plane for contact modeling

**Library:**Simscape / Multibody / Curves and Surfaces

The Infinite Plane block exports an infinite plane for modeling contact problems. You can model contact between the plane and many types of geometries, such as all types of solids and convex hulls in the Body Element library and the point geometry in the Curves and Surfaces library. Note that for contact, you must use the positive normal side of the plane for contact, which is in the direction indicated by the blue axis of the frame. Otherwise, the contacting part will be ejected to the normal side through the plane.

The Infinite Plane block is useful in planar contact modeling. For example, the Infinite Plane block is much more effective at modeling a ground plane than the Brick Solid block.
