What is a general moving object (GMO)?
A GMO is a rigid body in a FLOW-3D simulation that is intended to move or be moved by fluid. GMOs can have any type of user-prescribed motion, or the GMO can be dynamically coupled with the fluid flow. It’s no accident that with FLOW-3D, users can model collision between objects with the General Moving Object (GMO) model. Modeling fluid-structure interactions can include debris flows, opening and closing valves, counter-meshing gears, and big-particle collision. This robust model, the only one of its kind in commercial computational fluid dynamics (CFD) software, allows users to model rigid body dynamics with six-degrees-of-freedom (DoF) fully coupled with fluid flow. Some of the highlights of this powerful model are: • Allows up to 500 moving objects, each of which can possess 6 DoF, or rotate about a fixed axis or a fixed point. Other motion constraint patterns are also possible. • Objects can be fully coupled with fluid flow or the user can prescribe their motion. • Objects can be m
