Alex Grey. Fluid dynamics - Vic2d. Vic2d is a multithreaded two-dimensional fluid simulator. It uses a vortex-in-cell velocity solver with a 4th-order semi-Lagrangian method-of-characterstics and 4th-order interpolation scheme for advection. A similar method was mentioned in a 1969 paper (find reference), but does not appear to have been used since then.
Unlike Stam's stable fluids method, it is not unconditionally stable, but it does have the ability to take large time steps with very little numerical diffusion and subsequent loss of energy. Vic2d is a collection of C and Fortran files and requires only gcc, gfortran, and the PNG libraries to compile.
I wrote the base code in 2004 and have been using and updating it since then. Files The current version of vic2d is 1.0. Features Vic2d supports the following options (and more): 12GB of RAM will allow you to run vic2d on domains up to 12288 x 12288 or 16384 x 9216 with full-color scalar tracking. Images Future plans Future versions of vic2d may include the following: Thanks. 3D cube on oscilloscope - Tetalab. Electric Pink by WalkingShrub.

For years I've been throwing old computer boards into a box in the garage to someday recycle them into some sort of project. It finally popped in my head to create a table with them using some of the black walnut from a tree we cut down a few years ago and had milled in the yard with a portable mill. It's basically two tables. One internal table to screw the boards to and another set of wood frames with glass that slide on top of the board table. Fractal Images. Movie Ark.
