I'm pretty sure I have a proper fix for this now. It's pretty deep into the pipeline with multiple output ports and temporal information but pretty interesting in what it's doing.

Thank you for looking into this. I only modified the windbladereader to handle a slight format change, so my knowledge here is a bit limited (in regards to its original design) but I'll help out when necessary. From what I see there are two outputs (one field, one blade). I guess the nice thing about having a separate output for the blade is that I can render it separately from the field. <br>
<br>I can send you a data set with more timesteps (similar to what you are using now, actually), problem is my DSL connection has a poor upload. Would three or four timesteps do?<br><br>Sohail<div><br><br>--- On <b>Fri, 7/8/11, Andy Bauer <i><<a href="mailto:andy.bauer@kitware.com" target="_blank">andy.bauer@kitware.com</a>></i></b> wrote:<br>

The test file I have (<a rel="nofollow" href="http://vtk.org/gitweb?p=VTKLargeData.git;a=tree;f=Data/WindBladeReader;h=3459e8ded59eb05796e922d90200bd4e83231df0;hb=HEAD" target="_blank">http://vtk.org/gitweb?p=VTKLargeData.git;a=tree;f=Data/WindBladeReader;h=3459e8ded59eb05796e922d90200bd4e83231df0;hb=HEAD</a>) only has 2 time steps so I may need another set of files from you with more time steps.<br>
<br>Playing around with the reader in ParaView, I think it may be worse than you realize. Only the time information for the field is getting updated properly and if you go back in time steps, the blade time step either still increases or stays the same if it has hit the last time step. I need to talk to our temporal pipeline expert to figure out the proper behavior. One question though -- is there a reason that the reader doesn't return a multiblock with the 3 grids in it instead of having 3 separate output ports? I'm thinking that if the output was changed to a multiblock then these time issues would go away. <br>

I've noticed a bug when using the windbladereader; the portion of the code that reads the blade file is one timestep behind the code that reads the field. For instance, if one is at timestep i, the field data will correspond with timestep "i" but the blade data will correspond with the last timestep chosen. When a data set is opened initially both the blade and field items are set to the initial timestep. After one starts changing the timestep, the bug makes an appearance. <br>
<br>In the code, the blade and field specify their timesteps (individually) based on the bladeInfo and fieldInfo objects, respectively. These info objects are related to the outputVector of requestInformation -- I wonder if this is some kind of pipeline issue?<br>
