sorry for not responding immediately. Yes, you are right. We do not write an
intermediate VTK file, we just have a Paraview plugin. As far as I understand,
it relies on some NetCDF io routines in Paraview, which were written for
reading CF conformal data.
We also do only support triangles at the moment. Unfortunately, our
programming resources are very limited, and since no one is interested so far
in different meshes at our institution, we do not extend the plugin. But if
you have some data sets, which purely consist of triangular data, I would be
happy to test it and report back.
However, we probably still have to do some adjustments. I followed your
discussion about pyugrid about the naming of meshes, a question I also raised
to myself some time ago. We have to fix this as well for our plugin. It would
be nice if some text could be added to the convention to clarify such things.
