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
