Hi Sebastian,
unstructured grid support is indeed broken, I have opened bug #3337 at
http://bugs.mitk.org/show_bug.cgi?id=3337 . You can register at our
bugzilla site and cc yourself to the bug.
The file I loaded successfully was actually a vtk polydata, while your
.vtu files could not be loaded. I have created a first patch (attached
on the bug) which re-enables ug support in MITK, but it may still be
suboptimal. Maybe you can test it and tell me if it works for you?
Cheers,
Sascha
