<div>So I'm trying to use the Material Interface Filter:</div>
<div><br>
</div>
<div><a href="http://www.paraview.org/Wiki/ParaView/Users_Guide/List_of_filters#Material_Interface_Filter">http://www.paraview.org/Wiki/ParaView/Users_Guide/List_of_filters#Material_Interface_Filter</a></div>
<div><br>
</div>
<div>and have carefully created XML datafiles using vtkNonOverlappingAMR (*.vth) format. Unfortunately the v3.98.1 gui does not furnish the Properties option 'Down Convert Volume Fractions' when reading in the datafiles in *.vth format. (In fact the Properties
menu has only the 'Default Number of Levels' slider, and no cell data selector, and no 'Down Convert..' selector.) Consequently the Material Interface Filter has an empty choice for 'Select Material Fraction Arrays', and so the filter does not know what to
do. Alas, the only format that seems to generate the 'Down Convert..' option is *.spct, which, of course, we do not have in this case.</div>
<div><br>
</div>
<div>Is there another filter that I need to run prior to doing 'Material Interface Filter', or am I just plain out of luck here?</div>
<div><br>
</div>
<div>Thanks for your very capable help.</div>
