Surface, bodies & interactions

The InteractionPair module is designed to manage contacting surface and co-simulation surface pairs. All real load, constraint, contact pair and initial condition values are stored internally in double precision. The user may define and query load, constraint, contact pair and initial condition values in either single or double precision. The AnalyticSurface module is designed to manage analytic surface information. The RigidBody module is designed to manage rigid bodies.

Note that all contact pair and surfaces hold floating point data internally in double precision.
