It sounds like it. I believe that the user would have to use the extract
surface filter first though.

Andy,
Wouldn't the upcoming volume filter calculate the volume of fragments coming 
from the Connectivity filter?

Re: [Paraview] [EXTERNAL] Re: Material Interface Filter

[Cory Quammen]

As a happy coincidence, Will Schroeder just posted a merge request for
a VTK filter that computes the volumes of connected regions in a poly
data and stores the volumes in field data:
https://gitlab.kitware.com/vtk/vtk/merge_requests/3825. We could
expose this in ParaView once it lands in VTK.

I'm hesitant to add an option in the Connectivity filter to do this.
Instead, I can imagine uses for a volume computation for
surfaces/volumes labeled by a RegionId that isn't necessarily assigned
as a function of connectivity. Instead, I would prefer to create a
separate filter that computes volumes for each RegionId in the input
dataset. You would feed the output of the Connectivity filter to this
new filter and get the volume-per-region information you want.

The best way I can think of is to then use the threshold filter to isolate each 
of the pieces and then use the cell size filter on each piece. This would be 
fairly easy to automate in a Python script to just print out the values.
Alternatively, I don't see a reason why the Connectivity filter couldn't have 
an option added to output a field data array with the summed sizes of each 
piece. Since Cory just made the connectivity filter work correctly in parallel 
it would surprise me that he may be familiar enough with the code to do the 
change in a couple of hours.

Re: [Paraview] [EXTERNAL] Re: Material Interface Filter

[Scott, W Alan]

Bucky,
I believe that the problem is that - as you suggest below - the material 
interface filter only accepts down converted unsigned chars.  In my mind, this 
is a bug/feature hole.  Either, 1) the Material Interface Filter should accept 
down converted unsigned chars or default variables, 2) a filter should be 
created to convert to unsigned chars (with appropriate scaling), or 3) any 
appropriate reader should allow down convert .  Further, the Material Interface 
Filter has been hard coded to look for certain variable names (that it knows 
are down converted).  These are named Material volume fraction - # where #  
is 1, 2, 3, 4, etc or Volume Fraction - # where # is 1, 2, 3, 4, etc.


Berk - does this sound right to you?  I can think of one simple, short term 
option - I wonder if it is possible to write some simple python that would do 
the magic in a programmable filter?  Also, if you like, I can write up a 
bug/feature request.

Alan

So I'm trying to use the Material Interface Filter:

http://www.paraview.org/Wiki/ParaView/Users_Guide/List_of_filters#Material_Interface_Filter

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.

Is there another filter that I need to run prior to doing 'Material Interface 
Filter', or am I just plain out of luck here?

Thanks for your very capable help.
