CTF stands for Computational Turbulence Framework. That may be a little ambitious. Really it's a just hydrodynamics code with lots of room for expansion. It currently includes the following Lua modules as subdirectories, which are themselves independent projects managed through git subtree.

• Mara: Relativistic MHD turbulence code
• C.O.W.: "Cube of Wonder" analysis tools
• fish: Solvers for systems of conservation laws
• lua-hdf5: High-level parallel I/O with HDF5
• lua-mpi: Lua interface to the Message Passing Interface
• lua-glut: Lua wrappers for OpenGL and GLUT

Copy the Makefile.in.template file to Makefile.in, and modify it for your system, then type make.

There is an examples directory showing how to use most of the modules. Try something like this:

./ctf examples/tests-1d.lua soundwave -o output.dat

or if you have gnuplot installed,

./ctf examples/tests-1d.lua soundwave --plot

This code is made freely available for anybody's use. I only ask that if you find it useful, please send me an email about how it works, and in what project you are using it.

The CTF is licensed under the same terms as Lua itself.
