Instructions: -turbowarp for speed: https://turbowarp.org/1365141126?turbo -click to create/delete a wall. -space or play button to start the simulation. -you can edit walls during the simulation. -pressure is shown by color. blue is low pressure, red is high pressure. -flow direction is left to right. how it works: -pressure is the average of its neighbors, with the left side pinned at 1 and the right pinned at 0. -x speed is pressure on the left minus pressure on the right. -y speed is pressure above minus pressure below. -direction is atan(yspeed/xspeed) Credits: -all me :)
