I was myself doing a lot of CAD design before and I never thought that FEA Analysis was a big deal. This is what I thought: Take a CAD model, apply material, loads, boundary conditions, contacts, mesh it and then watch the results… it is like a black box. At least it is what I […]
Simplify Shell models for better meshing
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 […]
FEA problem solving- always begin from something simple
There are two kinds of problem in the world of FEA: easy ones and difficult ones. Haha…I’m joking. My point is that the difficulty to solve a particular problem depends on lots of factors that beginners in FEA may not know. And it makes them difficult to estimate the difficulty of their problems or even […]
FEA basics – CAD model simplification for FEA analysis
Today’s subject: CAD model simplification for FEA analysis. Why do you need to simplify your model? How can I do that? The most simple workflow for FEA analysis is: 1. Import CAD model 2. Mesh the model 3. Assign boundary and loads 4. Perform analysis Unfortunately, all may not go as smoothly as we want… […]
Plate with a hole analysis : FEA Basics
The plate with a hole ! Who didn’t start to learn FEA by this simple example ? I remember when i modeled for the first time this plate on the first NASTRAN in DOS during my FEM course, what a memorable moment… i had to run the program like a hundred times before getting a […]
The difference between CAD and CAE
This is a very basic subject that I would like to talk about, but it is fundamental to understand well that there is a world between this two words. I can always remember that when I had my first Computer Assisted Design (CAD) course in my engineering college in France (the Ecole Centrale of Lille), […]
