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

Tue Jul 17 18:57:34 EDT 2012

Sorry, but I meant to ask a different question.  Here's what Andy said before, which relates to my concern:

What I meant was; which ParaView class "creates" or "tests" a reader to see if it can handle a file? The test code you specified has a predefined data set that is loaded in, and I think is more of an example to your average user. Correct me if I'm wrong.

So basically ParaView will recognize the file extension, tries to load it, crashes somewhere, then asks you specify the data format from a dialog.  I'm trying to figure out where it crashes so that I can see how that relates to the wind blade reader class and any MPI calls that are in there.
