Samuel, Thank you very much for the timely help. The pvd example is very helpful. Although the client may still want all segments in a single file, at least we now know what tool to use for the segment-selection interface. I'll keep looking for a single-file format but I doubt there is any.
Thanks, Jimmy ------------------------------ Date: Tue, 08 Oct 2013 09:23:31 -0600 From: Samuel Key <[email protected]> Subject: Re: [Paraview] Which polygon file reader in Paraview has interface to show/hide separate segments? To: [email protected] Message-ID: <[email protected]> Content-Type: text/plain; charset="iso-8859-1"; Format="flowed" Jimmy, I have attached a file named 'fmavto.pvd' that is an ASCII-text file. It is a meta-file that references a series of XML-formatted *.vtu files. ParaView reads the *.pvd file and then knows how to "assemble" the files referenced within the *.pvd file. The important key-words in the *.pvd files are 'timestep=...' and 'file=...' Note that the individual *.vtu files contain the data needed for a displayable graphics object. The key-word 'name=...' is gratuitous user-information. The key-word 'name=...' for a couple of ParaView versions around 2007 would pass this user-information to the Extract Block filter; currently (PV version 4.0.1) the ASCII-text strings are no longer passed to the Extract Block filter. However, the Extract Block filter does reflect the structure implied by the *.pvd file; the filter simply uses the ubiquitous and not-very-helpful C-language off-set addresses of 0,1,2,3,... for the block names. Because of the large number of ASCII-text files that can be generated in a transient dynamic simulation with multiple material domains using the vtk-formats, sometime back I switched to the EnSight binary-formatted output. In this format it is possible to provide names that will appear in the Extract Block filter.
