Example: 2D Geometry
This example shows the interaction of 1 keV hydrogen with a circular cross-section of a B-N dust grain (composed of 50% B, 50% N by number).
This figure shows the cross-section of a boron-nitride dust grain exposed to a mono-energetic beam of 1 keV hydrogen. The trajectories of hydrogen are shown in black, boron in dark orange, and nitrogen in lighter orange. Hydrogen enters at the left side of the circular mesh, at y=0.
