[Paraview] CGNS files

Fri Sep 30 03:54:50 EDT 2011

That's what Robert already answered (see below) but it seems that type cgsize_t is not defined in cgnslib-2.5 (I downloaded it from this link: http://sourceforge.net/projects/cgns/files/cgnslib_2.5/Release%205/cgnslib_2.5-5.tar.gz/download):
Macintosh-4:cgnslib_2.5 $ find . -name "*" -exec grep cgsize_t {} \;
but is expected in PV source:
Macintosh-4:ParaView-3.10.1 $ find . -name "*.C" -exec grep cgsize_t {} \;                        if(cg_array_info(i+1, namenode, &dt, &ndims, (cgsize_t*)dims) == CG_OK)            if(cg_zone_read(GetFileHandle(), base, zone, zonename, (cgsize_t*)zsize) != CG_OK)                if(cg_array_info(i+1, namenode, &dt, &ndims, (cgsize_t*)dims) == CG_OK)    if(cg_zone_read(GetFileHandle(), base, zone, zonename, (cgsize_t*)zsize) != CG_OK)				 RealSingle, (const cgsize_t*)rmin, (const cgsize_t*)rmax, (void*)coords[c-1]) != CG_OK)				   (cgsize_t*)(&start), (cgsize_t*)(&end), &bound, &parent_flag) != CG_OK)                if(cg_ElementDataSize(GetFileHandle(), base, zone, sec, (cgsize_t*)(&eDataSize)) != CG_OK)                if(cg_elements_read(GetFileHandle(), base, zone, sec, (cgsize_t*)elements, NULL)    if(cg_zone_read(GetFileHandle(), base, zone, zonename, (cgsize_t*)zsize) != CG_OK)                               fieldname, dt, (cgsize_t*)rmin, (cgsize_t*)rmax,
so which cgns-2.5 source code did you use?or did I miss something in the cmake configuration file?

We haven't tried CGNS 3 yet with the VisIt reader. The binaries are built with CGNS 2.5 still.

Bad suggestion lolActually I downloaded the dmg file, indeed to check this, and I can read the file using the prebuilt version.

Did you try a cgns file from cgns web site ? Can you open your cgns file with the Windows browser, from cgns web site ?
My suggestion, had a look to your file first.

I have no problem to compile with cgns-3.1.3 but if I load a cgns file, I got the following error:

ERROR: In /usr/local/ParaView-3.10.1/Utilities/VisItBridge/AvtAlgorithms/vtkAvtSTMDFileFormatAlgorithm.cxx, line 409

vtkVisItCGNSReader (0x121793510): VisIt Exception caught.

ERROR: In /usr/local/ParaView-3.10.1/Utilities/VisItBridge/AvtAlgorithms/vtkAvtSTMDFileFormatAlgorithm.cxx, line 409

vtkVisItCGNSReader (0x121793510): VisIt Exception caught.

so what is this line 409 and what is wrong here:
      this->AvtFile->GetMesh(timestep, i, name.c_str()) );

I use cgns 3.0.8 with hdf5, without any compiling errors.
Works fine

Have fun

That looks like you are including 3.1.X as that line is a call to CGNS. A quick grep returns no usage of cgsize in the CGNS reader.

I was using the last version, ie 3.1.3, so I tried with the 2.5.5 but got a compilation error:
/usr/local/ParaView-3.10.1/Utilities/VisItBridge/databases/CGNS/avtCGNSFileFormat.C:331: error: ‘cgsize_t’ was not declared in this scope

I do not understand because cgsize_t is defined in the version 3.1.3 but not in the version 2.5.5 of cgns!

What version of CGNS do you have installed? We have only tested the reader using the 2.5.5 version of CGNS

The CGNS reader with the official 3.10.1 release can load the 5blocks test file.

Actually I finally got it!So now I have a CGNS reader but when I apply, I got the following errors:

ERROR: In /usr/local/ParaView-3.10.1/Utilities/VisItBridge/AvtAlgorithms/vtkAvtSTMDFileFormatAlgorithm.cxx, line 409

even with a - supposed to be valid - cgns file downloaded from here (the bump file): http://cgns.sourceforge.net/CGNSFiles.html

Can you please email me your CMakeCache.txt please.

Si I finally did it, skipping cmake to build cgns library, toggled options as written below and finally... still not abe to read any cgns file!I mean, same issue as before, ie if I select a cgns file, I am asked about which type of reader I want to use but no cgns reader in the list!

Hi Fred,
You have two options to enable CGNS in ParaView. The easiest is to use the SuperBuild process in ParaView which will automatically enable the VisIt bridge and the CGNS reader and build CGNS itself.

The other option is to manually enable CGNS support if you already have CGNS built. You will need to enable PARAVIEW_USE_VISITBRIDGE and set the Boost_INCLUDE_DIR. Once that is done you will need to enable VISIT_BUILD_READER_CGNS and set the CGNS_INCLUDE_DIR and CGNS_LIBRARY

I just compiled it but am unable to load a CGNS file - and CGNS is not included in the list of supported file formats - so I suppose I missed something in the configuration but did not see anything related to CGNS, please tell me which option has to be toggled.

ParaView 3.10.1 has CGNS support. It will support structured and unstructured meshes and will only read cell and point centered properties.

Hello,what is the current status of CGNS file support by PV?Thanks in advance for your answer.
