The basis is that within a grid, there is a rectangular portion, approximately one fifth of the total x distance and the entire y distance containing a number of particles, del_x distance apart (representing a fluid). At the initial position each grid has a horizontal velocity, and a vertical velocity. I am trying to simulate a scenario where the right boundary of the rectangle is suddenly removed, releasing all of the "fluid" So by assigning each grid unit within the rectangle 9 particles, I would essentially be assigning values to the free boundary (The right and top boundary), performing my calculations, resulting in a new horizontal and vertical velocity, determine the new velocity at a time n+1, and then compute the particle position. the problem would be creating a particle that would be tracked.
