Gravity drainage / 64 recorded border cells

Left: area glyphs. Right: actual finite-volume cell centers / A relative to initial mean. Both show the same recorded states. These are border cells, not moving film particles.

No state interpolation. Width is magnified for visibility. No film appearance is fabricated: this stage contains no film. No surfactant, gas, rupture or coarsening.
