Analytical rigid surface definition

An analytical rigid surface:

  • can be two-dimensional or three-dimensional;

  • must be defined as model data;

  • can be used with the infinitesimal-sliding, small-sliding, or finite-sliding mechanical contact formulations;

  • should be oriented such that the analytical rigid surface's outward normal points toward any body it may contact; and

  • is associated with a node, known as the rigid body reference node, whose motion governs the motion of the surface.
