[OpenFOAM] ParaView and Visit Readers Submitted

tj22 · August 23, 2006, 09:53

I have submitted OpenFOAM 1.3 readers to both ParaView(www.paraview.org) and Visit (www.llnl.gov/visit). You should see the reader in the cvs version of paraview in the next 2 weeks and in the next release and you should see it in the next release of Visit (in September).

Hi!

I've download Visit (www.llnl.gov/visit). It looks nice but I could not load OpenFOAM-data into it. The "Open File"-Dialog has the option to read in OpenFOAM, but it only lets me select files (not directories). I tried putting an empty file with the extension .foam in various places (like paraFoam does it), but that wouldn't help either. Am I missing something very obvious?

Select the system/controlDict.

gschaider · October 18, 2006, 13:43

Thanks, that did the trick.

Is there some documentation that says what works with the Visit-reader and what doesn't? Because I'm still having problems with some of my meshes (mostly wedge-meshes and cyclic BCs)

(Been looking around and the VisIt-site doesn't say too much about OpenFOAM, the Help-function doesn't know anything about OF and as far as I can tell there is no archive for the Visit-mailinglist)

tj22 · October 19, 2006, 14:47

There is no documentation available. Since I wrote it, I guess questions should be directed to me. My email address is in the reader source code.

Also the reader for paraview is available in the cvs but currently has some compilation problems on VC 6, so it is commented out of the Cmake file.

I have a problem which says

The metadata server running on host localhost has exited abnormally. VisIt is trying to restart it.

whenever i try to open an OpenFOAM file through opening /system/controlDict and filetype as OpenFOAM

this problem does not arise with the other file types.

something i am doing wrong?

I cant really help you with visit or even paraview without having your dataset.

The openfoam reader is available in the CVS version of paraview, and should be in the next release.

to use you must make a copy or rename "controlDict" to "controlDict.foam".

Hi, I experienced exactly the same problem as Iyer's on VisIt-1.5.4 for Windows when reading a tutorial case, tutorials/icoFoam/cavity (I haven't tried other cases). The case is run by the Cygwin version of icoFoam and corrected the 'root' keyword entry in controlDict from cygwin-style path to Windows-style path but it didn't work either. Just for your information for now...

tj22 · December 5, 2006, 12:33

Sorry for the delay, I just looked in to this and it seems to be a problem on the Visit side of things as none of the 3 readers I submitted are working. I have contact Visit and I will let you all know when I have a solution.

hartinger · December 6, 2006, 10:56

just use foamToVTK, works fine
visit can handle the VTK format

tj22 · December 6, 2006, 10:59

That kinda of defeats the purpose of a native reader. And if you want to go that route just use paraview.

hartinger · December 6, 2006, 11:05

yep, was meant as a quick-fix

another thing, is it possible to change the position of legends? I couldn't figure that one out and it really annoys me

hartinger · December 6, 2006, 11:07

i mean, the position of legends in visit

jens_klostermann · December 7, 2006, 04:48

Hi Terry,

Thank you for making the readers available. I just played a little bit with visit.

It works fine with simple cases e.g. flow in a square cavity, but with more complex geometry (all hexaeder, app. 160k cells) it is very slow and gives me always timeout errors like these:

Running: engine_ser1.5.4 -host localhost -timeout 480 -port 5602
Warning: Polyhedral Data is very Slow!
Running: engine_ser1.5.4 -host localhost -timeout 480 -port 5600

Why is it so slow?

Jens

tj22 · December 18, 2006, 16:15

I am not sure. I would be willing to debug it for you. Can you get me the dataset?

tj22 · December 27, 2006, 11:05

There are some issues that arose with the visit reader that should be corrected in the next release. Maybe you could try Paraview instead for the time being.

There is also an inherent problem in Visit with Polyhedral data (vtkConvexPointSet). So if your data contains the OpenFOAM wedge and tet-wedge, there are no corresponding VTK cell types so i used the vtkconvexpointset.

Terry,
Thank you for making Foam reader for VISIT.
I have been seeking way to display
"time" on animation.
Now I can do it using VISIT.

There is also a time label displayed at the bottom of the 3d view in paraview as part of the OF reader.
