Over 2000 validations of Code_Aster

Code_Aster is an open source software package for simulation in structural mechanics, including fatigue, damage, fracture, contact, geomaterials, porous media and multi-physics coupling. It was originally developed by EDF as an in-house application for safety-related simulations in nuclear energy environment. The software has been evaluated through independent comparisons in regards to analytical and experimental results and was benchmarked against commercial codes. Code_Aster is used for various applications by industry-leading companies including:

  • Airbus S.A.S.
  • Rolex SA
  • Valeo SA

Additional Open Source Solvers on the SimScale Platform


The CalculiX package was developed by a team from MTU Aero Engines as a tool to build, calculate and post-process finite element models.


SU2 is a toolkit for aerodynamic shape optimization and is under active development in the Aerospace Design Lab at the Department of Aeronautics and Astronautics at Stanford University.


Yade is an extensible open source framework for discrete numerical models, which allows the virtual simulation of the behavior of bulk material within industrial applications.


As the results of a simulation also depend on the mesh quality, our platform combines a large number of strong meshing algorithms which allow you to create accurate and robust computing grids in a short time.

Validation Library

Convince yourself – our free validation library provides you with a large number of evaluated simulations of standard scientific cases including the full simulation and the analytic results.
