I want to deprecate Xdmf2 and make Xdmf3 the default the next release. Because Xdmf3 adds a dependency on boost Xdmf will have to become optional in ParaView. The Kitware binaries will have it on because we already Superbuild in boost for the VisItBridge, but other versions could easily drop it. 2) Does 2D work properly? I don't think I tested that particular path in Xdmf3. If you can make a small test dataset which disproves its working, I'll likely be able to fix it and add it to the regression test suite for Xdmf3 in VTK. I guess this should work... ?xml version=1.0 ? !DOCTYPE Xdmf SYSTEM Xdmf.dtd [] Xdmf Version=2 Domain Grid Name=Unnamed Topology Type=TRIANGLE Dimensions=1DataStructure DataType=Int Dimensions=1 3 Format=XML 0 1 2 /DataStructure /Topology Geometry Type=XYZ DataStructure DataType=Float Precision=4 Dimensions=3 3 Format=XML 0 0 0 1 0 0 0 1 0 /DataStructure /Geometry Set SetType=Edge Name=Test DataItem NumberType=Int Dimensions=2 Format=XML 0 0 /DataItem DataItem NumberType=Int Dimensions=2 Format=XML 0 1 /DataItem Attribute Name=Set Values AttributeType=Scalar Center=Edge DataItem Format=XML Dimensions=2 1 0 /DataItem /Attribute /Set /Grid /Domain /Xdmf 3) What about Attributes which are not in a Set. The XDMF pages say this:- A Grid centered Attribute might be something like Material Type where the value is constant everywhere in the grid. Edge and Face centered values are defined, but do not map well to many visualization systems. But how do you define Edge and Face centered values for the whole mesh, anyway? Not sure I understand the question, much less the answer, but lets have a go shall we? Set's can have their own attributes and those attributes can be grid centered. So if the set has all the edges, then the set's grid centered attributes apply to all of the edges in the mesh. OK, I probably confused things by mixing this in. I'll ask it as a separate question. 4) Finally, is there any real need (in the case below) to go via the Faces? Maybe, before the standard gets more widespread, this could be eliminated, and just go direct from Cell-Edge... OK, this is just a suggestion... Could do. I can't think of a reason off the top of my head why vtk's cell-GetEdge is any less well defined than cell-GetFace()-GetEdge() and it is probably faster. Maybe that is why the bug is there in xdmf1/2. Yes, and this should also help to fix point (2) above, since Triangles don't have Faces, only Edges.

[Paraview] How to automaticaly generate probe location points?
Hi, I need to generate a wide variety of probe location points and plot selection over time, in 4 models. This demand a significant amount of time to do manualy.

Re: [Paraview] SWKey: Definitions of 'Q-Criterion' and the calculator's mag(*) operator? Revised w/ Answers
Hi Samuel, The issue with the symmetric tensor magnitude calculation is that ParaView doesn't know it's a symmetric tensor so it doesn't know that it needs to sum the off-diagonal values twice. All that is know for these arrays are how many components there are. A three-component array could be representing either a 3D vector or a 3D anti-symmetrix, second order tensor so it's the user's responsibility to compute the magnitude properly where shortened representations of tensors are used.

Re: [Paraview] File in pipeline browser has changed; best way to reload
Michael Christian, Thanks for your emails. I've been doing some other things, but am returning to this question. Michael, I am attempting to use the solution you proposed: http://public.kitware.com/pipermail/paraview/2013-June/028596.html However, when I try to adapt this to use ExodusII instead of Xdmf, I crash Paraview. I copied the code from the above link, and simply replaced 'Xdmf' with 'ExodusII'. When I try to load my xml file into paraview using the plug-in manager, that's when I cause the crash. I've successfully loaded the plugin in its un-modified form (e.g. the Xdmf form), so I must not be modifying the code correctly. I'm sure it's something exceedingly simple (I've tried replacing class=vtkExodusIIReader with class=vtkExodusReader for example), but I don't know what I'm doing wrong. Here is my code: ParaViewPlugin ServerManagerConfiguration ProxyGroup name=sources SourceProxy name=EXODUSRrefresh base_proxygroup=sources base_proxyname=ExodusIIReader class=vtkExodusIIReader Property name=Refresh command=Modified panel_widget=command_button/ Hints ReaderFactory extensions=e file_description=ExodusII Reader (Refresh button) / /Hints /SourceProxy /ProxyGroup /ServerManagerConfiguration ParaViewReaders Reader name=ReaderWithButton / /ParaViewReaders /ParaViewPlugin Any help from anyone would be appreciated!
