gmshToFoam troubleshooting

Would you mind pointing me in the right direction...

I think the error i am getting may be independent of the mesh. However I have attached the reference anyway(just load the .geo into gmsh and click 1D then 2D for final mesh)

The output:
.................................................. ....................

36038
36039
36040

P.S. im running Openfoam1.6 (git gcc compiled 12/14/09) on Ubuntu 9.10

Right now i think the error could be due to any of the following; gmshToFoam utility, compiler issues, Ubuntu 9.10 issues, my mesh, my control dic file. If you can knock one or more off the list it would be greatly appreciated.

Thanks guys!

I have managed to fix my problem. Unfortunatly I am not certian how. I deleted my mesh and started from scratch and what do ya know; it imported perfectly with gmshToFoam and checked out with checkMesh.

I have attached my working .msh file if anyone would like to use it to test their gmshToFoam function.

From that point I edited my boundary, v, and U file. The errors are pretty self explanatory at that point.

Maybe the file actually uploaded this time... :)

(the mesh file wont upload because it is too big; just open the geo file in gmsh and click Mesh>3D and save the mesh.)

it took me quite a while to debug my gmsh-FOAM setup, hope this helps someone (otherwise im just talking to myself in here :) )

cheers!

Eric,

I am trying your attached file, but something does not work. I can generate the mesh with gmesh, and I save it. When I do

gmshToFoam myAirfoil.msh

I get following error:
