Every engineer doing FEA Analysis probably knows that increasing the number of elements is supposed to improve the accuracy of the solution. This is true. But, this also create some problems, because if you are perfectionist (I know a lot of engineers are), you may be thinking something like: “If accuracy increases with the number […]
Analyze the Fluid Flow inside a Choke Valve
Today, I decided to write a post to explain simply how to perform an Analysis of the Fluid Flow inside a Choke Valve. This is a great exercise for beginners in CFD (Computational Fluid Dynamics) so I hope this example will prove extremely useful for you! The Software I am using is midas NFX CFD: You […]
Open Discussion: loads physical understanding in FEA
Yesterday, I got this message from an FEA engineer in Norway, Valeriy Shepenkov: My biggest challenge and the biggest challenge for most in the finite elements business is the loads physical understanding and their application in the FEA software. If you could provide some advice on how to effectively single out the essential loads and […]
Mesh Topology
Every FEA Analyst has his own story to tell with the mesh topology when I didn’t know what it was, I use to think that it was not so important…but then I had this model which was perfect in appearance but the analysis didn’t want to run and I kept having this message telling me […]
FEA Software is your golden goose
Do you know this Aesop’s Fable about the golden goose? This fable is the story of a poor farmer who one day discovers in the nest of his pet goose a glittering golden egg. At first, he thinks it must be some kind of trick. But as he starts to throw the egg aside, he […]
3 Skills of a Real Engineer
Have you ever wondered why an engineer is an engineer? Is it because he followed engineering classes and got his engineering degree? Is it because an engineer knows how to use correctly mechanical tools? I don’t believe so… I was an engineer much before that, I just didn’t know it! I started at five years […]
