MODELING If you want to get started with the rigid body modeling
you should be aware of that the modeling setup, mesh
displacement and rigid body motions are depended on the
complexity of your system. Maybe a mesh displacement can be
restricted to one domain, or a subdomain with sliding mesh is
sufficient to model the rigid body? We will help you with these
questions and will further recommend that you make a sketch of
your system to decide which parts are needed to be moved, this
will make the modeling of domains and interfaces in
DesignModeler easier. This tutorial will briefly show three
different ways of how to use the Rigid Body 6DOF solver in CFX
v.13. We hope this will be a good start if you want to begin
using the final release of the CFX Rigid Body solver. A rigid
body is a solid object that moves through a fluid without itself
deforming. Its motion is dictated by the fluid forces and
torques acting upon it, plus any external forces as gravit
