As you point out it seems as if the directory $ParaView_DIR points to is empty or non-existent.

It is set in .OpenFOAM-1.0.2/apps/paraview/cshrc (or baskrc)

Hi Mattijs

Tank you in advance for your help. How you can see in my last message, the variable ParaView_DIR is correctly set (I suppose) :-[ and checked it again:
[wladimyr@geitt4 ~]% echo $ParaView_DIR
/home/wladimyr/OpenFOAM/linux/paraview-1.8.0/lib/paraview-1.8

I ran the prompt command "ls $ParaView_DIR" and this directory exist and contains the ParaViewConfig.cmake file, as is demanded in CMakeCache.txt file.

Could you or somebody help me?

Many Tanks anyway

Hi!

I would like to recompile the PVFoamReader utility for Paraview (linux,i686). Is that possible at all without also recompiling paraview from source?
Following the instructions in this forum I have done

md8hemra@haif~/.../graphics/PVFoamReader> wclean PVFoamReader/
md8hemra@haif~/.../graphics/PVFoamReader> wclean vtkFoam/
md8hemra@haif~/.../graphics/PVFoamReader>./Allwmake

But this gives the error message:

The file "...lib/paraview-1.8/ParaViewConfig.cmake"
does contain paths to Henry's build. If I replace those paths with the ones corresponding to the OpenFoam installation, I get into more path problems later on.

I am wondering if it is of any use to keep looking to fix the path problems or if I should just give up and recompile paraview.

It is annoying the cmake preserves full paths in it's configuration files rather than relative paths which makes it difficult to transfer the builds. It should be possible for you to substitute your paths for mine in the relevant files but if that proves difficult it might be easier to compile paraview from scratch which is quite easy.

Ah, got it to work. Thanks for the help.
The problem I face at home is that compilation of Paraview takes a long time on my old computer..

Anyway, for future reference: To recompile the PVFoamReader class I had to
change the paths from /home/henry/ to /home/myUserName/ in

OpenFOAM/linux/paraview-1.8.5/lib/paraview-1.8.5/ParaViewConfig.cmake

I also needed to change

"paraview-1.8.5" to "ParaView" on line 26 in the same file.

old:
SET(VTKCS_SOURCE_DIR
"/home/myUserName/OpenFOAM/linuxSrc/paraview-1.8.5/Utilities/VTKClientServer")

new:

"/home/myUserName/OpenFOAM/linuxSrc/ParaView/Utilities/VTKClientServer")

Well. it is actually not working. Got PVFoamReader to compile, with the result that ParaFoam segfaults at start. I will try recompiling Paraview instead..

Hi,

To generate mpg movies, I now used foamToVTK to convert all the data to VTK and then read them back using paraview.

Can someone here post the steps how to generate mpg movie when invoking the paraview using paraFoam?

When I used paraFoam, I got all the time steps, but, I cannot get animation to work properly (slide bar of time steps moves, but, no redraw of the plot).

Thanks!

This sometimes happens with big cases. Switch off "cache geometry" and "record all properties" in the animation settings dialogue.

In the 'main' function of the solver, we have defined fvMesh mesh, volscalarField gamma.

Now,foamToVTK has been modified to meet my need and a likely right VTK file was got.

I don't know exactly the difference between vtkMesh and fvMesh. The vMesh is defined as follows:
vtkMesh vMesh
(
IOobject
(
meshName,
runTime.timeName(),
runTime,
IOobject::MUST_READ
),
cellSetName
);
I want to know if the point and cell data have been read into vMesh with the above code? If the mesh of my solver keep the same along the time, then whether the code
"polyMesh::readUpdateState meshState = vMesh.readUpdate();......"
in the time loop of my solver
"while (runTime.run()){......}"
should be removed?

Help me.

Another question, I want to know if vtkMesh vMesh can be constructed dircetly from fvMesh mesh? Or if we can convert foam data to VTK format without vtkMesh class?

Yes, when you construct a vtkM
 

Yes, when you construct a vtkMesh with an IOobject with MUST_READ flag it will read the whole mesh. (leave cellSetName an empty string)

It behaves exactly like a normal fvMesh with the difference that it holds the vtk representation (accessible through topo()).

You do not need the readUpdate if your mesh is static.

The vtk representation (vtkTopo) holds the vtk cell types and vertices and does automatic decomposition of polyhedral cells.

Sounds as if you're trying to do something hard. Good luck!

Hi, Mattijs, thanks for your help.
The VTK file achieved has the following lines.
CELL_DATA 12800
FIELD attributes 2
cellID 1 12800 int
gamma 1 12800 float //1 for scalar?

In my Visualization Toolkit, I can only find POINT_DATA instead of CELL_DATA. Which vtk class should be used? vtkUnstructuredGridReader,vtkUnstructuredGrid, or vtkFieldData? Can you tell me how to get the gamma field out in VTK?

Help me.
Thanks.

No idea. This is what I would do:
1. get a valid case with a gamma field and convert it with foamToVTK with the -ascii option and compare the output.
2. the name of the reader is displayed somewhere on the tab it creates when you read your file.

Hi,

can anybody tell me what advantages paraview has compared to Opendx; and disadvantages. I mean there must be some good reasons, not to support OpenDX anymore!?
Until now, I use OpenDX which is in my eyes pretty powerfull, but I am thinking about leaving OpenDX and just go deeper into paraview.

Greetings!
Fabian

- paraview runs without any us
 

- paraview runs without any user programming in combination with the foamToVTK converter
- paraFoam requires much less programming than the Open-DX reader (have a look at the complexity of the postFoam network)
- paraview uses much less memory.
- paraview can do distributed data.

There was never too much of a problem with Open-DX itself, it was all the programming nessecary to read and display OpenFOAM data. Paraview is setup to be a CFD postprocessor, OpenDX is an environment to quickly generate one's own postprocessor.

Hi, I'm having problems using paraview 2.0. Since I have an installed version of paraview 2.0 aleady running on my machine, I don't want to compile it again in openfoam. However, when I call
paraFoam icoFoam cavity
on the tutorial example, I get the following error message with paraview crashing

/home/oevermann/OpenFOAM/OpenFOAM-1.1/bin/paraFoam: line 57: 5357 Segmentation fault paraview paraFoam.pvs

Question: how do I get openfoam work neatly with a pre-installed paraview? Which environmental variables and configuration files do I need to set?

Thanks for any help

You will have to rebuild the OpenFOAM ParaView reader module for your pre-installed version of ParaView but the binaries released from KitWare do not include all the necessary build scripts to do this which is why we release ParaView binaries with OpenFOAM which include everything necessary to build the reader module. So the easiest way forward is for you to use the ParaView we release with OpenFOAM or if for some reason you are unable to you will probably have to build from sources.

I have similar problems. I installed paraview 2.0 to take advantage of the new animation and parallel post-processing capabilities and it is no longer compatible with the reader module.

If you do not want to downgrade to the supported paraview version, I suggest you use the foamToVTK utility to convert your cases to vtk format before post processing. At least that is what I am doing at the moment.

Henry, thanks for the note! I did built Paraview from source because there is no binary for G5 Mac's running Debian Gnu Linux. So, everything should be OK. How do I rebuild the reader module?

Thanks, michael

First change the environment v
 

First change the environment variable for the location and version of ParaView in
.OpenFOAM-1.1/apps/paraview/bashrc or cshrc depending on what shell you are using and source your ~/.bashrc or ~/.cshrc. Then goto OpenFOAM-1.1/applications/utilities/postProcessing/graphics/PVFoamReader
and remove the directories for your platform from PVFoamReader/Make and vtkFoam/Make and type Allwmake and that should build the reader module for you.

Hi,all. I want to use the VTK
 

Hi,all. I want to use the VTK lib in this directory "OpenFOAM/linux/paraview-1.8.5/". Whether the VTK contained in paraview has any difference to the original version from the web site of VTK? What is the version of my VTK located in "OpenFOAM/linux/paraview-1.8.5/"?

Under this folder
"\OpenFOAM-1.1\applications\utilities\postProcessing\graphics \PVFoamReader\vtkFo am\Make", I found the option file

EXE_INC = \
-I$(ParaView_INST_DIR)/include/vtk \
-I../PVFoamReader

LIB_LIBS = $(GLIBS).

What is the value of $(GLIBS)? I type "echo $GLIBS", it shows nothing. What should "GLIBS" be replaced by?

Thanks.

Alternatively, just experiment with the Filters. They are very easy and intuitive to use.
