Or first run the merge blocks filter.
Or just run the merge blocks filter first like the man says.
[But actually. The merge blocks filter, uses a vtkAppendFilter - which
is a memory hog - then you pass the output of this into another
appendfilter - on large datasets this will be terrible. Much better to
add multiblock support to the appendfilter so that it only has to do
the memnory allocation once.]

The exodus reader is no doubt exporting multiblock data, so the
SafeDownCast will fail. Add an extra test for Multiblock and then use an
iterator to loop over blocks and then safedowncast and do what you need
