CAD model Your model is not meshed properly or the mesher cannot even complete the meshing? This kind of problem happens to everyone, even the most skilled in FEA. Nowadays, CAD models tend to have too many details and so it is difficult for an analyst to simplify those models enough to get a proper […]
Learn the tips and strategies to mesh correctly your FEA model
You will find in this category all the articles I wrote about meshing. There are many things to know to be sure you get the best results out of your FEA meshed model. Read those articles to understand.
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. […]
Link 3D and 2D Elements with RBE3 Interpolation elements
This is a video which is short but effective… very few people actually know you can use interpolation elements to do that !
Get The Proper Mesh Density
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 […]
Why do FEA engineers use 1D, 2D, 3D elements ?
Yesterday, my Friend Apoorv Sharma conducted a webinar about FEM Modeling and the topic was quite popular as over 200 engineers registered to attend. I suggested Apoorv to include a simple poll about 1D,2D and 3D element types to see what the engineers that joined the webinar were thinking. If you want to watch the […]
Simple solution to overcome meshing problems
Today, I just have a stroke of Genius (up to you to decide if it is or not…) and I wanted to share it with you ! I will share with you a simple solution to overcome meshing problems I realized that many times when I performed the meshing process, the mesher stayed stuck at […]
