ANSYS
My career as a seismic and dynamic specialist engineer has meant a lot of finite element analysis. ANSYS is my software of choice, and I've got over 10 years of experience using this for all manner of simulations.
I wrote a guide to condense all my experience into one handy summary.
You might also like my free web app for Richardson Extrapolation, a method for confirming mesh convergence. This is for any finite element analysis software, not just ANSYS.
