HIRENASD Comparisons of FEM modal frequencies and modeshapes

Below are frequency comparisons of different models with experiment

<BR>Note Modeshapes aren't very descriptive for higher modes.  There is coupling between them so this is just an approximate naming scheme.  See modeshape plots for more details.
