[Paraview] xdmf & polygons

[Xavier Garnaud]

Hello,

I have a polygonal mesh stored in a cgns file and I am tryng to write the
corresponding xdmf files (to be more flexible than with a cgns reader).
I attached 3 simple examples: test_mixed works fine.xdmf works fine, the
other two do not.
In order to have a xdmf file that corresponds to the hdf/cgns dataset, I
would need to have the connectivity stored as
<Topology NumberOfElements="2" Type="Polygon">
          <DataItem Format="XML" DataType="Int" Dimensions="10">
          5 1 2 3 4 5 3 3 6 4
          </DataItem>
        </Topology>

- is it possible to define a topology with Type="Polygon" ?
- is it possible to use baseOffset with a polygonal mesh?

Thank you very much for your help.
Best regards,

Xavier
