<p class="MsoNormal" style="margin-bottom:12.0pt">The metadata is on the reader's output, which is a vtkMultiBlockDataSet. reader.GetOutput() should get you the dataset in your python script. Inside the programmable filter you will need to get the input dataset
(self.GetInput() should get you the input dataset and self.GetOutput() should get you the output dataset). So something like the following for your programmable filter:<o:p></o:p></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">Once again, I need help. We are starting to assign names to our Exodus blocks (outside of Paraview). This is very useful for ease and clarity of post processing and allows convenient
reference to actual components. The good news is that Paraview seems perfectly happy to read in the Block Names and use them in the Properties Panel and the Multi-block Inspector and the Find Data screen if they exist (no action or programming required for
this). So, for instance, instead of Paraview generating the non-useful name of “Unnamed block ID: 13 Type: hex” when the blockname is empty, it will automagically use the more useful Blockname of “Tread” if that is in the Exodus file.
<o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"> <o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">However, there has been an unintended consequence of this change. If I select some elements and examine them in Spreadsheet View, I see Block Number 14( the +1 offset from Block_ID
and Block Number is NOT the problem!). And now I can no longer associate the element (Block Number 14) with it’s block in the Properties Panel or the Multi-block Inspector or the Find Data panel – where the same block is called “Tread”.<o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"> <o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">So, to remedy this situation I would like to add an element variable of BlockName, which would contain “Tread” for all the elements in BlockID 13, etc., etc. for all the blocks.<o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"> <o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">My only problem is I can’t seem to find the list of Block Names. I’m pretty weak at vtk, so it must be available but I surrender – I can’t seem to find it. If someone can help
me find the list of Block Names from inside the Programmable Filter, I’ll be happy to add the element variable myself.<o:p></o:p></p>
