AutoPIPE's Modal and Dynamic Analysis Compared with Caesar II

Check out the comparison of Modal frequencies between Caesar 5.3 and AutoPIPE v9.4.1 at the linked PDF below:

UPDATE: As with testing previous versions of Caesar and AutoPIPE, similar results have again been validated on updated versions of Caesar (v8.0) and AutoPIPE (v10.1).

As you can see from the results of the comparison below, for simple models Caesar is missing many natural frequencies even using its consistent mass method. The frequencies it does report are not always accurate.
