-In this example, we choose a ``cylinder`` grid type to create a cylinder. Grid arguments are the radius of the cylinder (0.056 m) and half-length (0.051 m), respectively.  The grid is refined 3 times using the ``set initial refinement`` parameters. The ``expand particle-wall contact search`` is used in concave geometries to enable extended particle-wall contact search with boundary faces of neighbor cells for particles located in each boundary cell (for more details see `Rotating Drum example <../rotating-drum/rotating-drum.html>`_).
