• incorrect file input
  • pts
    • text
      • non numbers in the pts file
      • more points than indicated in the header
      • less points than indicated in the header
    • binary
      • NaN? and Infs
      • max/min beyond believable range.
  • elem
    • non-conformal faces
    • incorrect node numbers
    • invalid region numbers (>=0 ?)
    • invalid element types
    • zero volume elements
  • lon
    • no effect when used with fibers that aren't unitary.
  • vtx
    • incorrect header
    • incorrect node numbers in file
    • too many points in vtk file
