Well, I have written the code which reads the Star couples and creates the proper cells. This is a part of the starToFoam converter and everything should just work.

If you really want to do us a favour, you can dump the faces raw because I'm sure Harpoon needs to mess about with the native format to create Star couples in the first place. The easies mesh format I can imagine would be:
1) list of vertices
2) list of faces in terms of vertices; I don't care if they are polygons
3) there's options, whichever is easier for you:
- list of cells in terms of faces, i.e. all faces that belong to a cell, or
- "left" and "right" cell for each faces (for boundary ones, only one is required).

If you can provide this info, I cna take it from there.

Regards,

Hrv

The Fluent export would be the most useful.
It is probably quicker to finish off the FOAM export I started. Can I send you some files to test? If so, what email address should I use?

No probs - if needed, I will add the stuff into the Fluent export as well. The best E-mail is h dot jasak at wikki dot co dot uk.

Thanks,

Thanks to Hrvoje checking our meshes, the next release of Harpoon will have a OpenFoam direct export. This will be available in the next couple of weeks to download from www.sharc.co.uk

Will do. I have run some tests on it and it looks ok but would need more testing. Version will not be ready until end of next week at the earliest

Hi, Richard,

Can you explain how to export OpenFOAM using command line option? I am using Windows version and I cannot find a window for entering commands.
Thanks!

Hi, Richard,

I encountered a couple of problems when trying out Harpoon. The most serious one is that, after exporting the mesh to OpenFOAM format, these files (boundary/cells/points/faces) are not usable. When I tried to open the files, I got "this file is binary...". This occurred to both the 32 bit windows version and the 64 bit Linux version.

I am wondering how this can be resolved.

Harpoon is not ready for OpenFoam 1.3. But with OpenFoam 1.2 it should work!

Whats wrong with binary files? What does checkMesh say?

The OF 1.3 mesh constructors are backward compatible with 1.2 formats so there should be no issue.

I have tested the new Harpoon release and there was always the same problem with OF 1.3 (same failure as described above). With OF 1.2 all works fine.

So it has definitly something to do with the version of OF and/or the way how the meshes are created in Harpoon so OF is able to read them.

I have found out why the harpoon exported mesh does not work under OF1.3.

The boundary file has been written in DOS format and the handling of the DOS characters have changed between 1.2 and 1.3.

To fix the problem execute the following command:
dos2unix -n[list=1] <newboundaryfile>

This works on the test case I received. Could someone please confirm the fix.

The problem is probably that you are using the single precision version. Harpoon exports the data in double precision

the harpoon export works fine with OF1.2 and OF1.3 but as Eugene has already mentioned one have to convert the boundary file (ASCII) from the dos to unix format!

I think the following 2 options were very useful in order to use harpoon with OpenFOAM:

- boundary file in unix format (instead of dos)
- save the exported files as boundary, cells, faces, points and not as xxx.boundary etc.

I am trying to use Harpoon as a mesher for OpenFOAM... i am now using OF 1.4.1 under Ubuntu 7.10 32 bits...

Anyone has experience running Harpoon unde Linux x32 Kernel 2.6.x?

I can start the gui... and i can mesh geometries, but once i try to export in any format, OpenFoam, Fluent, CFX5, shell states that it cannot get Global nears... and no export file is created...

Any hint on what might be happening?

Thanks for your time

Alex
