"WebInline means that the cylinder is oscillating parallel to the incoming flow. This kind of configuration is often used to validate solvers aiming to simulate large body motions (see e.g. [1, 4, 5]). The reason is that that despite its simplicity this configuration is associated with a variety of complex physical phenomena. " - Openfoam rotating cylinder
