Hi i'm using ANSYS CFX which i found to be relatively easy to work with

What about free (cost)? Ages ago the ASME CD ROM had Phoenics on it. Are
there any CFD on SourceForge.net or GNU.org? These packages are monstrously
expensive these days. It is nearly impossible for someone out of the field
to keep up. Or for a student to learn alone.

Then comes interoperability. Unless you want to write MicroSoft DDE code.
Increasingly I understand MatLab (or Octave/SciLab clones) is preferred
because the data is already in the system and doesn't need fancy conversions.
eg, you compute the CFD but then you want to optimise the shape of the
boundary (like Joukofsky, but for the reactor wall, or the prosthesis wall).

Dear Vasos,

My recollection is that the version of Phoenics you could
get for free was severely limited in what it could do.

I have never used it, but you might want to look into
OpenFOAM. It appears to be a pretty capable CFD package
that is available under the GNU GPL.

Other free packages are available, but many of them are
specialized for particular types of problems. These
might or might not be suitable for you depending on
whether you need compressible/incompressible,
inviscid/viscous, simple geometry/curvilinear grids, etc.

hi
actually i have no idea about this software
i m learing cfd, and right now using only the theoritical conept of
plane fluid dynamics
if , somehow i will get any news about this
i will send the required information

Many thanks. Am I right that OpenFOAM is primarily Linux?

From their web site it sure looks that way.
Of course, with the source code available you should be
able to build an executable to run under the operating
system of your choice, but there may be some issues
related to the graphics-intensive pre and post
processors.

As I said, I haven't tried using it myself. Perhaps
some one else out there can help. If you Google
OpenFOAM you will find discussion groups -- perhaps
someone there can help.

Running under Windows is more difficult. The source code files use .c for C
files, and .C for C++ files. Some of the files have the same name, with only
the extension differemtiating between them. Windows is not case-sensitive at
the file level, and thus the source code trashes itself when unpacked from
the archive file.

*If* you wish to use Windows, then the following sites may be helpful:

http://dpdx.net/openfoam-cygwin/ -- core engine
http://oshima.eng.niigata-u.ac.jp/Op...-20070224.html
-- GUI

CAELinux comes with OpenFoam 1.2. The Windows versions above target 1.3. And
OpenFoam has released, last week, 1.4.
