"Fluid" is program which solve incompressible, viscous, free surface fluid flow. It use The Mac Method to solve Navier-Stokes equations on Euler 2D grid. Algorithm is able to support 3D geometries but it is not included in the program. See examples of Fluid computations. You can find there a lot of .mpeg files created with that version of "Fluid". Solve Navier-Stokes equations with this tool.

Fluid Features:
1. full differential implementation of navier-stokes incompressible equations on euler grid
2. free surface tension implemented
3. THE MAC METHOD(marker-and-cell) used to tracking particles and typing surface
4. poisson equation for pressure solved with relaxation method
5. complex boundary conditions which support slip, and no slip boundaries
6. algorithm easy possible to expand for 3d geometries
7. full user interface created with FOX library
8. easy structure of option files
9. a lot of physic properties easy to change
10. stability condition possibly to change from program level
11. output no several frames, but .avi file
