If you ever started to do linear static FEA Analysis, you probably encountered the following singularity error: ERROR : 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. […]
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.
This is a video which is short but effective… very few people actually know you can use interpolation elements to do that !
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 […]
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 […]
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 […]
If you follow the posts on my blog or if you are experienced in FEA meshing, you know how the quality of the model is important in order to get better mesh and results. Recently, i just discovered a new method to simplify Shell models in midas NFX ! And all that in Video S’il […]
