MATLAB fractional step code

April 24, 2006, 13:38

For anyone interested, I have recently made a 2D unsteady Navier-Stokes solver available (free!) at:

http://www.mathworks.com/matlabcentr...bjectType=file

The code (Navier2d) is based on the fractional step method and uses a 2nd order upwind FVM for discretisation on unstructured meshes. There is also an automatic mesh generator.

Before anyone starts abusing me, I am aware of a few things:

1. There are heaps of CFD codes around - This is not supposed to compete with commercial packages.

2. Most people here use more "hard-core" languages like C or FORTRAN - Universities tend to teach engineers MATLAB now, so I simply used what I know. The critical components are written as C source modules anyway, so I don't expect a fully C implementation to be THAT much faster...

3. This is just where I'm up to. I will be updating the code in the future.

I've benchmarked the code using the standard cases, as well as some more complex problems and haven't seen it do anything terribly wrong (yet!!)

Hoping that this will be useful,

Darren

The CFD-Wiki/source_code_archive for codes is sitting out there practically unused.
