Distribute points using the rtz cylindrical coordinate system. This results in 264 points arranged around the z- axis. There are 3 rings of points at distances r=1., r=2. and r=3. from the z-axis. There are11 sets of these three rings of points and heights z=0., z=1., z=2.,…,z=10. In each ring there are 6 points where each pair of points is separated by 60°; note that ijz=0 requests that points be placed at cell centers, hence the first point will be at 30° not at 0°. Corresponding to r=0, there will be 6 identical points at 11 intervals along the z-axis at heights z=0., z=1., z=2.,…z=10. Filter should be used to remove these duplicate points. Note: Cylinders are open but finite. To create a closed cylinder cap both ends with planes.
