In this Salome Meca Tutorial, we will go through one of the most complex simulation on this channel, a leaf spring simulation with 3 distinct types of nonlinearity: Nonlinear Material, Large displacements and Nonlinear contact !
I chose to divide this tutorial in 2 parts because it is a very complex simulation and there are many intermediate steps we need to go through to get it right.
In the first part, I have first setup a simple elastic study of the spring alone and I have created a nonlinear material simulation of this spring.
If you haven’t watched the part 1, I highly recommend you to do so, because you need to understand those basics for the part 2.
In this part 2, I will show you how to change the geometry and the mesh and how to define the nonlinear contact correctly and get the convergence of the solution.
Here’s the video:
Here’s what I will talk about in this video:
- Introduction
- The Simulation Problem
- Simplifying the geometry
- Meshing the Spring
- Meshing the Plate
- Creating the Mesh Groups
- Discussion about Contacts in Code_Aster
- Setting up the Model
- Debugging the Simulation
- Solving the Contact Convergence
- Notes about utilisation of Contacts in CA
- Real time result monitoring
- Review of the final solution
CAD Model, and All simulation files are available here on Github:

This is the best documentation about contacts in Code_Aster:

(Check the French version if you speak French, it is way better…)
