Description

This project provides open-source librairies to solve the Navier-Stokes equations based on Jos Stam paper, and an interface to simulate a fluid in 2D.

The source code can be found in the following directories:

solver : solving librairies;
display: interface.

Instructions

  $PATH_TO_BIN/FluidSolver

Use the option -h or --help to show the usage message.

This message shows the different options available.

For instance, the option -config can be used to restore a previously saved configuration, with the actual screen resolution. (see -lconfig to list saved configurations, more details in the help screen)

Shortcuts

Keyboard

  SPACE .......... Pause / Resume the simulation
  ENTER .......... Change display mode
  F .............. Reset the fluid
  R .............. Reset the fluid and the sources
  BACKSPACE ...... Reset the system (fluid, sources & obstacles)
  V .............. Toggle velocity field drawings
  M .............. Toggle mouse velocity modifications
  + .............. Increase cursor size
  - .............. Reduce cursor size
  F1 ............. Toggle fullscreen
  Ctrl-S ......... Save the simulation
  Ctrl-O ......... Restore a saved simulation
  ESC, Ctrl-W .... Quit

Mouse

  Left button ........... Inject fluid density
  Right button .......... Remove fluid density
  Ctrl  + Left button ... Add a density source
  Ctrl  + Right button .. Add obstacle
  Shift + Left button ... Add a directionnal source
  	    a) first click to set the source position
        b) second click to set direction and speed

  Wheel Up ....... Increase cursor radius
  Wheel Down ..... Decrease cursor radius

Leap Motion (experimental)

Any movement of the fingers tips in the vertical plane above the Leap Motion will be translated as a velocity modification. If a finger tip is crossing that plane, some fluid density will be injected into the system.
