We noticed that there is no particular way to save a volume mesh. We
need to export the meshes for ANSYS FLUENT. How can we accomplish
this?

detailed file specification, I don't mind writing a
converter.

When I try opening a FLUENT mesh file (.msh), it looks a bit
complicated. I'm not sure that I can make much sense of it. I did
find a source online which somewhat describes how the files are
structured. Again, it seems a bit complicated, but perhaps it might
make more sense to you? :)

I also found this discussion on the cfd forum about converting STL
files to FLUENT meshes, and it seems that it cannot really be done...
http://www.cfd-online.com/Forums/fluent/33918-stl-file-mesh-surface-problems.html
If you need a sample .msh file for comparison, I can upload one (i'm
not sure how to do it directly on the forum).
Just let me know.
Thanks.

iso2mesh supports STL and binary STL files, both added recently:

you'll have to download the svn version to use them

Hi,
I am trying to find a way to export volume mesh generated in iso2mesh
to CFD simulator as well. Theoretically, I should be able to just use
the STL file from iso2mesh to generate volume mesh in the simulator,
but I haven't succeeded yet. But iso2mesh is very easy to use and
generate a volume mesh for me quite nicely.
I wonder if Qianqian has got the time to write a converter to FLUENT.
Though I am using OpenFOAM instead of FLUENT, but conversion between
them is generally simple.
Thank you so much!
Best,

were only tested on meshlab. I don't have a copy of
FLUENT unfortunately.
I will be happy to modify the script to support FLUENT,
but I think it is more important for you to find out what
STL format does FLUENT accept. If you can share a
working sample, that can help a lot.
Once again, contribution from anyone is highly
encouraged, that is the whole idea of making it
open-sourced.
