[Paraview] Xdmf writer with multiple cell types (UNCLASSIFIED)

Karl,

The vtkXdmfWriter is not yet up to date with the new version
of XDMF. I think it can handle basic geometry but nothing
complex. Until it's fixed, the best you can do is to run 
the data thru a triangle filter first to make it all tets.
But I doubt that's what you're looking for.

There is a mixed topology type in the new version of XDMF
so supporting it that way will be an option. Otherwise it
would be GridType="Tree" with two "Uniform" children :

<Grid GridType="Tree" ...
	<Grid GridType="Uniform" ..
		<Topology TopologyType="Hex" ..
	<Grid GridType="Uniform" ...
		<Topology TopologyType="Wedge" ...
</Grid>

Subject: [Paraview] Xdmf writer with multiple cell types


I'm getting an error trying to write an XDMF file with different cell  
types (wedges and hexes).   Looking at the source code this appears to  
be generated from the vtkXdmfWriter.cxx line 1322.    Does anybody  
have a sense for the difficulty of removing this constraint?

    Thanks,
        Karl
