Being able to solve FEA problems is a skill, and this skill is trained by knowing the correct process to solve an FEA problem. Those steps are extremely important and if you learn how to develop correctly your thinking to assess each of these steps correctly, you will be able to become very quickly an […]
CAE Simulation for Beginners
Learning CAE isn't easy when you come from a CAD Design background, because it involves a very different engineering mindset!
The articles in this category will help you to understand the main concepts.
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 […]
product design FEA can be used mainly in 3 ways in product design: – As a tool for designers to help to create the right design -As a tool to check the design -As a tool to check the reasons why a product fails Designing a product is a challenge Designing a product is not […]
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. […]
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 […]
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 […]
