+Finally, we must alter the way that Gale creates particles.
+ The inflow boundary condition will naturally create a space devoid of particles.
+ Gale then creates new particles to fill that void.
+ Normally, Gale looks at nearby particles and replicates them.
+ However, nearby material has already changed a little from the boundary,
+ so replicating them will not give the new particles the correct properties.
+\newline
+To
+ fix that, we create a thin layer next to the boundary where material is
+ created anew.
+ So first we create this shape
