Mapping of plot3d data to OpenFOAM case

Fransje · June 14, 2010, 05:43

Dear all,

With little luck in the Preprocessing / FoamX subpart of the forum, I've decide to repost my question here.

I would like to map channel flow data from a 33 x 33 x 33 mesh in plot3d format on an OpenFOAM mesh, as initial condition. I have the geometry file and the .q file belonging to it.

Now, the grid can be easily converted to OpenFOAM format using the plot3dToFoam utility, but I wouldn't know where to start to generate a OpenFOAM U file from the plot3d .q file. Apparently there used to be a short description of the U velocity file structure in the UserGuide of previous OF versions, but not anymore. I was therefore wondering whether somebody might have experience with this type of conversions and/or could shed some light on the U file structure, which would be a great help in my quest of a viable conversion strategy / solution.

Looking forward to your replies!

Francois.

Hi Francois,

Did you find a solution to this problem? I am also interested in this procedure...

Cheers,
Felipe

Hi,

I am a beginner so I am not able to answer your question. I have a question for you.
How did you generate the plot3d file? Can I use plot3d in matlab?

Thank you for your help.

Regards
Jan
