Code_Aster is a software package for finite element analysis and numeric simulation in structural mechanics originally developed as an in-house application by the French company EDF. Code_Aster represents by now 1,500,000 lines of source code, most of it in Fortran and Python, and is being ... [More] constantly developed, updated and upgraded with new models. Justifying quality labels required by nuclear industry, most of the fields of the software have been validated by independent comparisons with analytical or experimental results, benchmarks towards other codes. Beyond the standard functionalities of a FEM software for solid mechanics, Code_Aster also compiles specific research in various fields : fatigue, damage, fracture, contact, geomaterials, porous media, multi-physics coupling.

The TFEL library is a collaborative effort of the French Atomic Commission and Électricité de France. TFEL mostly includes the MFront code generator. MFront is based on C++ and provides several domain specific languages which were designed to simplify the implementations of new material ... [More] properties, mechanical behaviours and simple material models. A particular focus was made on mechanical behaviours which are by essence more complex and may have significant impact on the numerical performances of mechanical simulations. For mechanical behaviours, MFront introduces interfaces for various finite element or FTT solvers (Cast3M, Code-Aster, ZeBuLoN, Abaqus Implicit/Explicit, Europlexus, AMITEX_FFT, etc..). [Less]
