Class
    Foam::RBD::restraints::propellerDiskForce
 
Description
     rigidBodyPropellerDisk force restraint.
 
     Applies the opposite force and moment of the propellerDisk onto the body
     the propeller is attached to.
 
Usage
    Example applying the propeller force and moment to the floatingObject:
    \verbatim
    restraints
    {
        force
        {
            type        propellerDiskForce;
            body        floatingObject;
        }
    }
    \endverbatim
