[Paraview] ParaView thinks that it does not have a wind blade reader

[Sohail Shafii]

I'm afraid my knowledge here is a bit limited.  All of my edits have been in relation to loading the blade data.  The MPI calls were put in by someone else.


By the way, is the wind blade reader updated in VTK as well? (i.e. the VTK package)  I remember downloading VTK a while ago and there was a mismatch between that windbladereader and the one in ParaView.

Hi Sohail,

I went through the code and it jogged my memory about previous problems with it. It had an explicit MPI call in the constructor that would cause problems when paraview wasn't getting built with MPI. Any time a user tried to open an unknown file it would try to create a windblade reader to see if the reader could handle the file and this would cause a crash. If you launch a separate pvserver the wind blade reader will be available in the gui.

If someone fixes this problem in the reader we can enable it properly through the gui. Right now though I'm getting a bunch of warnings when running in serial like:
Warning: In /home/acbauer/CODE/ParaView/ParaView/VTK/IO/Parallel/vtkWindBladeReader.cxx, line 942
vtkWindBladeReader (0x3a0c800): WindBladeReader error reading file: /home/acbauer/DATA/VTKLargeData/Data/WindBladeReader/test1_topo.wind Premature EOF while reading block of data. Expected 896000 but got 0

I get the same problem in both 3.14.1 and master. The reader is still available but just not conveniently through the GUI. To access it though you can bring up the python shell and do the following:
