[petsc-users] PETSc recommended visualization packages: Xdmf and HDF5

[Brad Aagaard]

Blaise-

I constructed my Xdmf writer based on the documentation at 
http://www.xdmf.org/index.php/XDMF_Model_and_Format. The documentation 
is vague but I was able to figure most things out with a little trial 
and error.

An example pair of HDF5 and Xdmf files is attached.

The code is in the PyLith repository available at
http://www.geodynamics.org/wsvn/cig/short/3D/PyLith/trunk/libsrc/pylith/meshio/?rev=18708&sc=0
The Xdmf object takes an HDF5 file (that we wrote so we know its layout) 
and writes the corresponding Xdmf file. The Xdmf.hh, Xdmf.cc, HDF5.hh, 
and HDF5.cc files are all in this directory.

Regards,
Brad
