Default Cell volume : face-center in 3d ?!?
Posts: n/a
I try to FILE->EXPORT cellvolumes of a 3d mesh in ASCII format. It appears that if I choose a "at Center" location, Fluent 6.2 gives the cell volume at each cell FACE center, but not at the VOLUME center -ie, I get a line for each FACE of the mesh, but not 1 line per 3d-cell. Does anyone know how to fix that ?

Moreover, I also export files in EnsightGoldCase format to get cells connectivity and nodes coordinates, but Fluent doesn't seem to sort nodes in the same order as it does when I export in ASCII format, so I can't fix the problem by using cellvolumes "at nodes".

Solution found by Fluent's HotLine :

ASCII file-export can only sort you cellvolumes at the center of the volume if you select no surface zone. When you got several cellzones, and you want the data for just one of them, you can only select Surfaces in the export window, and so get the center of the cells surfaces.If you select no surface, you will get the cellvolumes at the center of the volume, but for all zones of your mesh, not sorted by parts or zones.

If you want the volumes of the cells for one single zone, deactivate the zones you don't need, just keep the one you want, then ASCII-file-export cellvolumes 'at center' selecting no surface of your zone.

Hope it may help somebody someday
