Model of a rigid bottom ring of a net cage. Based on CToCollar written by Finn Olav. This is a rigid ring with six degrees of freedom. The number of connection points to the net may be set freely. Currently the physical properties are diamater and total mass. The moement of inertia is determined from these (based on the assumtion thin ring). The ring is visualized as a plain torus in bottomring.mesh, with 40cm tube diameter and 50m ring diameter. A scale factor of 0.01 is used for this mesh.

The class extends from C6DBody, but uses only the dynamics calculation from this class.

Todo:: To be added: Hydrodynamic forces Toroidal MI calculation and thickness parameter Mass per unit length parameter (50-80kg/m ?)
