FEA Vibration 201: Shock and Awe

Posted by Mark Decker on Jun 27, 2019 9:30:00 AM

The majority of simulation work I do now is with fluid flow and heat transfer using Computational Fluid Dynamics (CFD).  However, my career was first launched doing structural analysis with Finite Element Analysis (FEA).   I am old enough that my first FEA programs in college were written in Fortran and performed using batch computing

Degrees of Freedom – Mixing Solid, Shell and Line Elements in Nastran In-CAD

Posted by Robert Smith on Jan 22, 2018 9:16:19 AM

What are “Degrees of Freedom” when working with FEA models and why do they matter? If you're new to FEA, this is a good concept to get a grasp of early on. If you are experienced, you may not have ever run into any problems related to degree of freedom limitations in finite elements – or maybe you have and just didn’t know it.

Units in CFD and FEA plus Free Flow Calculator Utility

Posted by Mark Decker on Mar 13, 2015 7:40:00 AM

During a recent Google search, I stumbled across this interesting NASA paper which determined the root cause for the loss of the Mars Climate Orbiter in 1999 was a mismatch of units. A subroutine coded for thruster data in metric units was instead fed English units, which resulted in a trajectory error.
