hello,
How do you write the output of the extract CTH parts filter to either pvd or vtk file \
format using python script? Using the PV GUI, the menu option save geometry will save \
the output to pvd formatted files.
I am using ParaView-4.1.0 on RHEL 5- 64bit (and RHEL 6 64bit). If I open PV and \
source a box, and then open up the Python Shell and to the following
> > > from paraview.simple import *
> > > writer=CreateWriter("/home/simonsm/filename.vtk")
> > > writer.UpdatePipeline()
> > >
it will create the filename.vtk file with the box in it.
However, in PV, using the GUI to load a CTH file and then apply the extract cth parts \
filters, and the do the following in the Python Shell,
> > > from paraview.simple import *
> > > writer=CreateWriter("/home/simonsm/filename.vtk")
> > > writer.UpdatePipeline()
> > >
I got the following
ERROR: In /home/utkarsh/Dashboards/MyTests/NightlyMaster/ParaViewSuperbuild-Release/paraview/src/paraview/ParaViewCore/ServerManager/Core/vtkSMWriterFactory.cxx, \

The same if I run the following script via pvpython (python script at the bottom of \
this email). It will create the image.png file but not filename.vtk file.
