|Is there a way to import data from FLUENT ?
|AFAIK OpenDx can only handle the dx format, HDF and CDF.
Fluent 6 can export to DX format (File->Export...->Data Explorer), with
either surface or volumetric elements.
There are a few bugs in their exporter you could hit, but there are
workarounds. Here are the ones I know of:
1) Exporting surfaces can generate invalid object numbers in the DX
file. I have a script that will fix these.
2) Exporting volumes (i.e. don't select any surfaces; you get
volumetric elements instead of surface elements; e.g. tetrahedra
instead of triangles) yields toasted data. Looks like Fluent
randomizes the order of the velocity vectors. One of the guys here
just falls back to using Fluent 5.4's DX exporter which works in
this case.
3) Be careful with "Select All" variables (the black button above the
selector list) for volume exports in either Fluent 5 or Fluent 6.
The DX file might not work. A few of the variables are defined
multiple times resulting in name collisions. You can tweak the DX
file, or (simpler) just don't select the more than one of each of
the two duplicates in the list (here, cell-equiangle-skew and
cell-equivolume-skew).
I filed these with Fluent earlier this year, and they say they have them
fixed in the latest.
