[vtkusers] Hexahedrons in unstructured grids with bad aspect ratios

[Sarah Macumber]

Does VTK have any known problem drawing Hexahedrons with bad aspect ratios?  I can get VTK to draw the points but not the cells.  I have been going over my data for a while & can't find any problems with the data or the cells.  I included an example cell below.
 
Any help is appreciated,
Sarah
