Contains information about an immersed boundary in the flow.
The number of boundary points and the reference x- and y- coordinates of the boundary points are provided. The motion of the body is also described. For uniform motion, the translational velocity needs to be specified. For uniform rotation, the angular velocity has to be specified. You can also provide options for oscillations in the x and y directions, as well as pitching (rotational) oscillations. When the body rotates, the center of rotation must be provided too.
