Re: [Paraview] How to pass array from Server to Client with as 'Information Helper"

[Michael Jackson]

THANKS! that worked great. One last item - where would I look for an  
example of have a custom widget (QListWidget) that is NOT getting  
registered with the proxy mananger, so that when something changes,  
like the selection, the "Accept" button gets "lighted up". I am trying  
to work through the pqContourWidget but not sure if that is the best  
place to start.

Re: [Paraview] How to pass array from Server to Client with as 'Information Helper"

[Michael Jackson]

The problem is down in a generated file on the server side.

  if (!strcmp("GetNeighborList",method) &&  
msg.GetNumberOfArguments(0) == 3)

{
vtkClientServerStreamDataArg temp0(msg, 0, 2);
if(temp0)
  {
  op->GetNeighborList(temp0);
  return 1;
  }
}

The problem is that msg.GetNumberOfArguments(0) returns 2 and NOT 3. I  
have no idea of the internals of the msg object to try and figure out  
what is trying to be passed. Is the client sending in a index also? 2  
pointers? no idea.

[Paraview] How to pass array from Server to Client with as 'Information Helper"

XdmfGridAttributes.xml mentions only one file :

$PARAVIEW_DATA_ROOT/Data/RodPlate/RodPlate.xmf

When I load this file in paraview there are many data arrays but they
are all zeros except for "MaterialID" which is all ones.

Re: [Paraview] Paraview: python script from the command line

[Rick Angelini]

Utkarsh - this also works well under some circumstances, but leave it to 
the customers to figure out how to break it.   If we startup paraview:


paraview --server=Host --script=myscript.py

And "Host" is a reverse-connection, the python script executes locally 
without waiting for the remote server to start up.

Re: [Paraview] vtu: how to represent variation in cell end values?

[Berk Geveci]

The only way to define discontinuities like that is to split cells. So
you would have:

Cell1: point1 -> point2
Cell2: point3 -> point4

where point2 == point3. I know it is a waste of memory but it is the only way.

Re: [Paraview] Python scripting: Updating PVDReader source when pvd file has changed and rendering latest time step

[Florian Rathgeber]

Translating that to Python as I understand it would correspond to:
reader.FileName = ""
reader.FileName = original

That does the trick, thank you! I had tried that before and had hoped
there is a nicer way, since I get VTK errors about not being able to
open the file and read the file information on the terminal and the
output window.

Re: [Paraview] TecPlot problem or question for alternative format

[Zhanping Liu]

Try removing 'K = 1' from the zone header to see it the Tecplot reader
works. As Berk suggested, you may converted the data to legacy VTK.

Re: [Paraview] TecPlot problem or question for alternative format

[Berk Geveci]

I suggest legacy VTK (http://www.vtk.org/VTK/img/file-formats.pdf). It
sounds like this is a structured grid. One thing: VTK formats (and VTK
itself) does not directly support 2D so you will have to add a Z
value. Setting all Zs to 0 should work fine.

Is this ParaView cvs head or 3.8 branch? I don't think that you need a

Re: [Paraview] vtu: how to represent variation in cell end values?

[Berk Geveci]

Emily,

It sounds like you need point data not cell data. Point data arrays
contain a value per point (those values are interpolated to obtain
values that are in the interior of the cell), cell data array contain
a value per cell (which is assumed to be constant across the cell).
VTK will interpolate point arrays linearly over a cell of type Line.

The two data servers are spinning which reminded me of an openmpi bug so
I stuck "btl_sm_num_fifos = 15" in ~/.openmpi/mca-params.conf but that
didn't help. I got back traces for the render server and the two data

Re: [Paraview] Algorithm causing reader RequestData when running

[Burlen Loring]

If I'm not mistaken, when creating a VTK pipeline inside of a PV filter, 
you need to make a shallow copy of the input dataset in order to keep 
the PV pipeline isolated as your VTK pipeline executes.


Try making a shallow copy of "input" and passing that into 
"extractBlockFilter", and see if it helps.

VTK_CREATE(vtkExtractBlock, extractBlockFilter);

extractBlockFilter->AddIndex(1);
extractBlockFilter->Update();
output->ShallowCopy(extractBlockFilter->GetOutput());

return 1;
}

Can anyone see what I am doing wrong or provide any pointers for where to look?

No, I did not skip anything, this is the data I have. The X and Y
coordinates
are just data values as the following RHO, U, V, ...

So the TecPlot file is not valid?

Which simple file format for 3.6.2 do you suggest to convert the data to?

Thanks,

pv.XdmfReadStructuredGrid.XdmfReadStructuredGridCollection.XdmfGridAttributes

I got an "Output Messages" window that says :

ERROR: In /home/kevin/kitware/ParaView3/VTK/IO/vtkPNGReader.cxx, line 53
vtkPNGReader (0x4bdb950): Unknown file type! Not a PNG file!

This text appeared on the console but I could not reproduce it.

I tried to narrow the problem down so I ran each of the three parts
separately. The XdmfGridAttributes.xml part is failing.

Re: [Paraview] Problem compiling plugin for using with ParaView 64

[Michael Jackson]

YES. You need to use the proper command prompt from the start menu  
when compiling Qt to make sure you get the correct type of build (32  
vs 64 bit).


AFTER you have then built Qt correctly, then launch CMake-GUI and  
configure ParaView to build using a clean build directory. MAKE SURE  
YOU select the "Visual Studio 9 2008 x64" as the generator.

Hi Rafael,

Did you set VTK_USE_64BIT_IDS to OFF? If not that might very well
explain your problem on 64 bit. See also

[Paraview] Algorithm causing reader RequestData when running

[Paul Edwards]

Hi,

I am writing an algorithm to operate on a vtkMultiBlockDataSet where I
would like to extract blocks depending on field data that is set.
Internally in my algorithm I am using the vtkExtractBlock filter and
when this is updated it causes the RequestData for my reader to be
executed again.  This doesn't happen when applying ExtractBlock in
ParaView.  Below I have included an example RequestData that causes
the data to be reloaded (note: this only happens when running in
parallel):

8<-
int vtkTestMulti::RequestData(
vtkInformation* vtkNotUsed(request),
vtkInformationVector** inputVector,
vtkInformationVector* outputVector)
{

vtkInformation* inInfo = inputVector[0]->GetInformationObject(0);
vtkMultiBlockDataSet* input = vtkMultiBlockDataSet::SafeDownCast(
inInfo->Get(vtkDataObject::DATA_OBJECT()));

vtkInformation* outInfo = outputVector->GetInformationObject(0);
vtkMultiBlockDataSet* output = vtkMultiBlockDataSet::SafeDownCast(
outInfo->Get(vtkDataObject::DATA_OBJECT()));

VTK_CREATE(vtkExtractBlock, extractBlockFilter);
extractBlockFilter->SetInput(input);
extractBlockFilter->AddIndex(1);
extractBlockFilter->Update();
output->ShallowCopy(extractBlockFilter->GetOutput());

return 1;
}
->8

Can anyone see what I am doing wrong or provide any pointers for where to look?

Thanks in advance,
Paul

Re: [Paraview] TecPlot problem or question for alternative format

Farian:

It seems the Tecplot file does not provide the section of x and y
corrdinates (before the solution) at all, or you just skipped it at your
e-mail for simplification purposes?

Re: [Paraview] Problem compiling plugin for using with ParaView 64

[Rafael Castaneda]

No, I actually didn't do anything different when compiling the 32 and 64
versions of ParaView. Just checked "BUILD SHARED LIBS", that's all.

There are some flags in CMAKE which I'm not certain what value should I set.
For instance there is a flag CMAKE_CXX_FLAGS which is set to /DWIN32.
Shouldn't be /DWIN64 or something ? Also, as I compiled with Visual Studio
2008, should I have compiled some sorte of "Qt 64bits" ? I noticed that in
Start Menu I have "Visual Studio 2008 Command Prompt" and "Visual Studio
2008 x64 win64 Command Prompt". Should I have compiled Qt with the second
one ? As I'm not sure which one I've used, I'm compiling Qt again...

Thanks,
Rafael March.

Re: [Paraview] Dashboard Failures from *.hooperlab

Hey Kevin, For those 5 can you run them by hand and see if you notice why
they are hanging/failing? On some of them it looks like pvserver might be
crashing? Can you attach a debugger and see if you can get a stack trace?
Thank you very much for offering to help.

[Paraview] Problem compiling plugin for using with ParaView 64

[Rafael Castaneda]

Hey all,

I have programmed a plugin, and I want to get it to work with ParaView
3.6.2  32 and/or 64 release, distributed in the website www.paraview.org.

I compiled ParaView 3.6.2 with Qt 4.3.5 Opensource in release mode, then
pointed the plugin to this version with Cmake, compiled in release mode, and
it works fine: I manage to download the ParaView 3.6.2 in the website and
load my plugin on it. This was made in a Windows Vista Ultimate 32bits
machine.

Now I want to compile it for 64 bits version. I took the source from
ParaView 3.6.2 and Qt 4.3.5, compiled them in a Windows 7 Professional 64
machine, and compiled the plugin pointing to this version. The plugin
compiles and works fine with my self compiled version of ParaView. But, when
I download the 64 (or the 32) version of ParaView in the website, I can't
load the plugin ! It says something like: "This is not a valid Qt Plugin"
when I try to load it. But I'm sure I matched the version of ParaView and
Qt, 3.6.2 and 4.3.5.

Does anyone know what might be happening ?

Thanks in advance,
Rafael.

[Paraview] TecPlot problem or question for alternative format

[Fabian Wein]

Hi,

I got a code which exports data (LBM) in a very simple format:

---
TITLE=" LBM data"
VARIABLES = "X", "Y", "RHO", "U", "V", "VOR"
 ZONE T = "Z"
 I=  351, J=  122, K=1,  ZONETYPE=ORDERED
 DATAPACKING=POINT
 DT=(SINGLE SINGLE SINGLE SINGLE SINGLE SINGLE)
11  0.000D+00  0.000D+00
0.000D+00  0.000D+00
21  0.000D+00  0.000D+00
0.000D+00  0.000D+00
...
---
The format of point data is: x, y, several scalar data values

I was told this is TecPlot and the guy uses TecPlot for visualization.

I exchanged the format "D+" by "e+" and opened the file with the CVS
version from 03/25/2010.

The file is recognized by the TecPlot reader but the geometry of the
visualization is not correct.

I understand that TecPlot is quite complicated (I saw just the number
of pages in the data format docu).

I assume that it is more easy for me to convert the simple data to a
structure that PV 3.6.2 can read.
What is the most simple PV format for this?

Thanks,

Fabian
