Thanks for the answer, but it still doesn't work well for me.<br>I have changed solution to 3 components. Paraview doesn't issue a warning, but neither does it<br>show u initially, although 'Vectors="u"' is present. I attach the file, maybe you could explain why this happens.<br>
As for the Paraview bug, I tried to report it yesterday, but apparently I have to pay a $5000 subscription fee to get support:)<br> About the adapter, I tried:<br><br>vtkwriter.addVertexData(new PDE::VTKGridFunctionAdapter<PDE::DiscreteGridFunction<GFS,U> >(PDE::SelectComponentAdapter<PDE::VectorDiscreteGridFunction<GFS,U> >(udgf,0),"u");<br>
<br>This gives me:<br><br>no type named ‘LocalFiniteElementType’ in ‘struct Dune::PDELab::PowerCompositeGridFunctionSpaceTraits<Dune::GridView<Dune::DefaultLeafGridViewTraits<const Dune::YaspGrid<2>, (Dune::PartitionIteratorType)4u> >, Dune::PDELab::ISTLVectorBackend<1>, Dune::PDELab::GridFunctionSpaceBlockwiseMapper, 3>’<br>
<br>Could you tell me the proper way to use it?<br><br>best regards,<br>Oleh Krehel<br><br><br><div class="gmail_quote">2011/3/29 Jö Fahlke <span dir="ltr"><<a href="mailto:jorrit@jorrit.de" target="_blank">jorrit@jorrit.de</a>></span><br>

</div>Ah, OK. You are indeed right. However, I still fail to see why ParaView has<br>
the problem with that: the attribute 'Vectors="u"' simply means that u is the<br>
vector field that is initially shown by default when ParaView first opens that<br>
file. If you remove that attribute, ParaView simply shows some solid color<br>
initially, but later you can simply select the field u and ParaView handles it<br>
just fine (although there _are_ some rough edges, like the list where can<br>
select components showing component numbers 0 to 5 while the color legend<br>
shows components 1 to 6).<br>
<br>
If that attribute is there, ParaView will complain initially. If you ignore<br>
the error message however, you can simply continue as in the case without the<br>
attribute.<br>
<br>
I suspekt this is a bug in ParaView. Would you be so kind to report it to the<br>
ParaView guys (or check whether they have fixed it in a later version<br>
already)?<br>
<br>
Thanks,<br>
Jö.<br>
