People think just because they buy a FE software package it makes them a structural engineer and/or dynamicist. The sad thing is these people treat FEA as a "black box" because they do not understand the theory behind the FEM nor its limitations. Also, with the latest trend to build multi-million DOF 3D FE models makes it even more dangerous because zero thought goes into understanding load path, etc. - this leads to GIGO and dangerous, poorly engineered designs. I also find it funny how people in this thread have stated you "test" the design using FEA which shows you how little they know
