Frequency Study Validation

I am having trouble validating the results of frequency studies in SW Simuation with published results and analytical calculations. In particular, I found a published result online that documents a frequency study performed in MATLAB and ANSYS with very close results that I cannot duplicate in SW Simulation. Here is the link to the document

SW Simulation does not even indicate the same mode shapes. Has anyone else tried to validate a frequency study?
