<p>Daniel,</p>
<p>I am not sure this a solution you will want?<br>
</p>
<p>I have unstructured meshes that have several (1 to 38) material
domains. I use the EnSight gold binary format for my results. This
format has a Part-construct. When writing out simulation results,
each material domain becomes a distinct Part (distinct displayable
graphics object). <br>
</p>
<p>PV's Extract Block filter allows me to select and display any
combination of "Parts." From there, I am pretty sure you can
execute the steps you want.</p>
<p>Regards,</p>

<div>But the "GenerateIDs" filter removes the material array
from the dataset so I can't apply the Threshold filter
anymore. I see the "Extract Selection" works only with the
current IDs anyway that are different from the original cell
IDs due to the Clip filters. </div>

<div>How can I have a filter that extracts a certain set of
cells that I define and apply it to other .vtk files?</div>
