Free Open Source Software
I am keeping a list Free Open Source Software (FOSS) and related sites on this page.
Computational Fluid Dynamics
OpenFOAM is an excellent, open source CFD package. We use it extensively in our research group. Incompressible, compressible, laminar, turbulent, LES, DES, RANS, URANS + more. Full source code available and the ability to add your own solvers, utilities,… check it out. Actually, openFOAM can do more than just fluids. This is from their website:
“The OpenFOAM (Open Field Operation and Manipulation) CFD Toolbox can simulate anything from complex fluid flows involving chemical reactions, turbulence and heat transfer, to solid dynamics, electromagnetics and the pricing of financial options.”
OF 1.5 Released: now with snappyhexmesh – automatic meshing from STL files. Fluent/CFX – r u nervous?
A three-dimensional finite element mesh generator with built-in pre- and post-processing facilities.
Not quite FOSS, but listed anyway.
Math and Matlab-Like Packages
Python front-end + so much more. Can run from a web browser. Also check out the cool SageTex latex package that integrates latex with Sage.
Excerpt from Sage Website:
A long running and maybe the best GNU alternative to matlab. Check out the website, download it and go.
From Octave:
” GNU Octave is a high-level language, primarily intended for numerical computations. It provides a convenient command line interface for solving linear and nonlinear problems numerically, and for performing other numerical experiments using a language that is mostly compatible with Matlab. It may also be used as a batch-oriented language.”
Another excellent matlab-esq scientific mathematics package.
From website:
” Scilab is a scientific software package for numerical computations providing a powerful open computing environment for engineering and scientific applications.
Scilab is an open source software.
Since 1994 it has been distributed freely along with the source code via the Internet. It is currently used in educational and industrial environments around the world.
Scilab is now the responsibility of the Scilab Consortium, launched in May 2003. There are currently 25 members in Scilab Consortium.
Scilab includes hundreds of mathematical functions with the possibility to add interactively programs from various languages (C, C++, Fortran…).
It has sophisticated data structures (including lists, polynomials, rational functions, linear systems…), an interpreter and a high level programming language.”
LaTeX
Latex front end for Macs.
Complete TeX Live 2007 distribution + front ends. Evry thing you need to run latex on your mac.
Tex Live distribution for all platforms
How-to
Youtube for nerds. How-to videos for everything FOSS.
