Boundary conditions: -Neumann at the center of the meteorite (r=0), no molecules can leave from this boundary. -Open at the edge of the meteorite (r=rmax), molecules can leave from this boundary. Initial condition: -Constant concentration from r=0 to r=rmax, except for a smoothly decreasing concentration to zero at the outer edge of the meteorite (rmax).
