Re: [Paraview] Attribute for grid collection

Thu, 04 Apr 2013 00:57:36 -0700 

you must put the attributes inside each grid:

<?xml version="1.0" ?>
<!DOCTYPE Xdmf SYSTEM "Xdmf.dtd" []>

I have a domain that consists of patches of orthogonal cartesian grids in the following XDMF file:

The grid is declared as GridType Collection. When I read it in Paraview the grid is read correctly as shown in the attached picture, however I don't get the values for the attribute. I think the attribute is not read at all. Is there sth wrong with this file? How should the attribute be specified for GridType Collection? 

Thank you,

Nikos
