Hi Sohail,<br><br>Changing the number of fields from 23 to 16 fixed the warnings. I'll get these changes into VTK and then change ParaView so that it can read in WindBlade files with a single process. That may take a week or so though.<br>
<br>As for the other questions:<br><br>1) If the data directories are called VTKData, VTKLargeData, and ParaViewData and they share the same parent directory as VTK or ParaView, when you build VTK or ParaView it will automatically pick up the path to each of them.<br>
<br>2) For the library names, after modularization they've been changed and relocated from the bin subdirectory to the lib subdirectory. Many of the old libraries have been subdivided into better organized libraries. I don't know any specific document that specifies what to do for this though.<br>

I have some time now, so I addressed the issue. I don't the code has a problem; the problem is related to the .wind file. <div><br></div><div>Near the bottom, it describes how many fields exist in the comp.out files ("DATA_VARIABLES"). For your test data, each file is about 64.5 MB. The .wind says that each file should have 23 fields. For n scalar fields, 1 is reserved for UVW; (n-1) for scalar data. So for this one, 1 for UWV while 22 for scalar data.</div>
<div><br></div><div>The UVW block is about 10 MB (160x80x70x(4 bytes)x(3 components)); each scalar field is about 3.6 MB (160x80x70x(4 bytes)). So 10 MB + 22 scalar fields*3.6 gives you about 90 MB. That's way too big compared to the actual sizes of the comp.out files that you guys have for testing. <b> The test works when you reduce the "DATA_VARIABLES" item from 23 to 16</b> (which will give you close to 64.5 MB).</div>
<div><br></div><div>I'm not sure why this .wind file is bad. Maybe older wind blade readers just ignored errors like these. Anyway, the test seems to launch a window and close right away. I didn't see any other errors after I fixed the wind file that I am using.</div>
<div><br></div><div>A couple of questions:</div><div>1. How do you organize the VTK build directory with the testdata? The VTK tests seem to expect the data to be four directories UP the hierarchy, so I had to place my vtkData directory in my home folder.</div>
<div>2. I tried the new versions of VTK with QT and it appears that the -l commands that I put in the .pro file for linking (i.e. -lvtkIO) don't seem to work...is there a document somewhere that helps in this regard? I reverted to an older version of VTK for now but I want to eventually upgrade.</div>

<div>I finally got around to doing the VTK part of the WindBladeReader work. It's on gerrit at <a href="http://review.source.kitware.com/#/c/7734/" target="_blank">http://review.source.kitware.com/#/c/7734/</a>. It still needs some cleanup but at least both the serial test and the parallel test with a single process pass. For the serial test, vtkIOGeometryCxx-TestWindBladeReader, I'm still getting the following warning which needs to be fixed as well:<br>
Warning: In /home/acbauer/CODE/VTK/VTK/IO/Geometry/vtkWindBladeReader.cxx, line 568<br>vtkWindBladeReader (0x1373840): 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<br>

In today's git master it now sits in VTK/IO/Parallel/vtkWindbladeReader.<br>
<br>
The serial version should go in VTK/IO/Geometry.<br>
<br>
The MPI version should go in a new module VTK/IO/MPIParallel.<br>
(VTK/IO/Parallel depends only on vtkSocketController now and should<br>
not depend on vtkMPIController).<br>
<br>
Finally when that is done we can remove the flag in paraview's xml<br>
that prevents it from being used in serial.<br>
