Hallo guys,<br>
<br>
have a bug using xdmf + hdf5 in Paraview that I cant seem to solve:<br>
<br>
I am trying to visualize my results from a finite element
computation using xdmf and hdf5.<br>
<br>
The results consist of the geometry and topology of the mesh and
different point and cell data.<br>
I store coordinates of 2 million points in one hdf5 dataset (X,Y,Z
components) and the connectivity of the resulting 19 million cells (
hexagonals and lines ) in a one dimensional hdf5 dataset.<br>
<br>
I use the following xdmf file to view the data in paraview<br>
<br>
<?xml version="1.0"?><br>
<!DOCTYPE Xdmf SYSTEM "Xdmf.dtd" []><br>
<Xdmf><br>

<br>
<br>
<b>Question:</b> For some strange reason the cell connectivity gets
completely messed up, and I get a totaly wrong output in Paraview. <br>
I verified the content of the hdf5 file and all the points and cells
are correct.<br>
<br>
The hdf5 is about 5 GB large.<br>
<br>
Does anyone know how the cause of this strange behaviour? I tried
visualizing the content in visIT but got the same error. <br>
<br>
thanks in advance<br>
