Both ".k" and ".key" are used for input decks. The output files are
binary (not ASCII text) and are usually named "d3plot", "d3plot01", ...
Because the output files don't have any extension and because ParaView
uses file extensions to identify which reader to use, the
vtkLSDynaReader will take an input deck filename and try to find an
output file in the same directory. Sorry, but you'll need to run LS-Dyna
on the .k/.key files before you can use VTK's LS-Dyna reader to view the
models in them.
