A lot of companies now are talking about the « cloud » but not everyone knows what it actually means… As you might be required at some time or another to run your FEA “into the cloud”… better understand what is means ;-) As usual, let’s break down what it means and make everything simple to understand […]
How to Implement the Lattice Boltzmann Method (LBM) with a single relaxation time collision operator
This article complements and enhance the first article published on the blog about the LBM Method: Everything you need to know about the Lattice Boltzmann Method Today, the article will focus on the practical implementation of this method! I leave the place now to the author of the article, my friend and engineer Nicolas Maquignon.Implementation of […]
A Story about FEA principles
When you work with FEA for a long time, it’s only natural to wonder about the initial physical principles behind the software we use every day… It’s nice to have a graphical interface with buttons, ways to draw and make calculations… but where does all of that comes from and what are the physical equations used […]
How to face a singularity error?
If you ever started to do linear static FEA Analysis, you probably encountered the following singularity error: ERROR [2007]: FACTORIZATION FAILED DUE TO A SINGULARITY AT TRANSLATION-X OF NODE 111 (RANK=5262) What is the cause of this singularity error? This error is generated when matrix decomposition cannot progress any further due to the presence of singularities. […]
What is an FEA Solver ?
It’s been a long time since the last time I wrote on the blog, but FEA is an area where there are a lot of things to explain and I will continue to explain the contents which interest most of FEA engineers. Thanks to Fisible for proposing today’s subject ;-) I am waiting for your […]
