[Paraview] [Non-DoD Source] XDMF crash

Wed Jan 25 13:24:48 EST 2017

From my understanding of your method, you want to use the progression of "time" to iterate across attribute displays?

You don't need GridType="Subset" for that (and I don't think Xdmf3 uses that designation anyway). Just use XPointers to point the grids to the topology and geometry of the first one.

________________________________

Hello Mr. Burns, thank you very much for your helpful answer. I changed the XDMF file. But now I have another question. 

Now I have problems with GridType="SubSet". ParaView doesn't view the second and third timestep. Their grids are referenced as SubSet from the first grid. 

This is the reason why I am doing all this: I want ParaView change the color on a static, fixed, large geometry as quickly as if I switched the surface coloring variable in the Active Variables Controls dropdown, but using the time playback features. It is very inconvenient to change the "timestep" by selecting an other variable in a Color Map drop-down menu with thousands of entries. Is this even possible in ParaView?

This is my XDMF content:

<?xml version="1.0" ?>

	This is because the Xdmf3 reader does not support the Hyperslab Timetype. One Time item per grid is the preferred method.

	________________________________

	I generated the following XDMF file and tried to open it in ParaView. When I open it, I get a dialog with three readers to choose:
	- XDMF reader
	- XDMF3 reader
	- XDMF3 reader (Top Level Partition)

	I can open the file with "XDMF reader", but when I open it with the other two readers, ParaView (5.1.0 64-bit Mac) crashes.

	Application Specific Information:
	terminating with uncaught exception of type XdmfError: 'Value' not in itemProperties in XdmfTime::populateItem
	abort() called

	But I generated the file according to this recommendation < Caution-Caution-http://www.paraview.org/Wiki/ParaView/Data_formats#Reading_a_time_varying_Raw_file_into_Paraview < Caution-http://www.paraview.org/Wiki/ParaView/Data_formats#Reading_a_time_varying_Raw_file_into_Paraview >  >  and according to the XDMF3 < Caution-Caution-http://www.xdmf.org/index.php/XDMF_Model_and_Format < Caution-http://www.xdmf.org/index.php/XDMF_Model_and_Format >  >  standard. When I try to open this public example < Caution-Caution-http://www.paraview.org/Wiki/ParaView/Data_formats#Reading_a_time_varying_Raw_file_into_Paraview < Caution-http://www.paraview.org/Wiki/ParaView/Data_formats#Reading_a_time_varying_Raw_file_into_Paraview >  >  with XDMF3 in ParaView, it crashes, too.

	Now this is the content of my XDMF file:
