Hello all,
I am attempting to write some code in c++ which uses the vtkPVDReader from the
paraview library to read a series of vtm files. However I am encountering some
problems and I am not sure whether there is something I am missing or whether
this could be a bug.
I am trying to use the read
Hi Bogdan,
here are some issue in your code:
vtkSmartPointer pReader = vtkPVDReader::New(); // <== Memory
LEAK
// Should be either
// vtkNew pReader;
// vtkSmartPointer pReader =
vtkSmartPointer::New()
Then here on a "NULL" object you try to call a method.
vtkMultiBlockDataSet* pMultiBlockData
Hi Seb,
Thanks for the quick reply. Yes the project is managed with CMake. I have not
however been able to find the relevant posts by Marcus (in the users list). Is
that in the users or developers mailing list?
It does sound like it could be a problem with some initialization, as you can
see be
If you provide the stack trace, that may be helpful.

Certainly. I should mention, I am using a pre-compiled version of Paraview 4.1
bundled with Salome (Ubuntu package).
Here it is (using pReader->SetForceOutputTypeToMultiBlock(1)):
ERROR: In
/misc/dn47/SALOME/PRODUCTS/7x/opt/Ubuntu.13.10.64/7.4.0/tmp/ParaView-4.1.0_SRC/ParaViewCore/VTKExtensions/
Thanks Bogdan,
that's not helping me but someone else might have some idea.

Hi Bogdan,
You are writing a stand alone C++ app right? Are you setting up to run
the composite data pipeline as in the following example?
100 vtkCompositeDataPipeline* cexec=vtkCompositeDataPipeline::New();
101 vtkAlgorithm::SetDefaultExecutivePrototype(cexec);
102 cexec->Delete();

Hi Burlen,
Yes, it is a stand-alone C++ application, which makes use of VTK and Paraview
as libraries, linking against them and calling functionality to interpret the
data.
I am not setting up any pipeline (as of now). Is this from the TestExodusTime
or TestTemporalFractal examples. I will try
Unless something's changed in the pipeline recently that I'm unaware of,
when dealing with multiblock data you still need to force the composite
data pipeline first. that may or or may not be the cause of your
segfault, but you need to do it.

Bogdan,
The deal is this: the vtkPVDReader is designed for ParaView, it uses
some of the core client-server infrastructure in ParaView. Thus, you
can't use it directly is a VTK-based C++ executable without
initializing ParaView environment. Initializing ParaView environment
is not too complicated.
Burlen, Uktarsh,
Thanks for the clarification. I will give this a try and write back.
This might actually also help me with another problem I am having at setting
the timestep for which I want to fetch cell/point data.
This also has to be done from the pipeline object, right?
Kind Regards,
Bog
Hi Uktarsh, Burlen,
The PVD reader is finally working, thanks for the suggestions.
Initializing the environment before using the PVDReader is what did the trick.
Should it be useful to somebody else, you can use something akin to the
following for initialization:
static vtkSmartPointer
