What is Metafor?

Metafor is an object-oriented Finite Element code for the simulation of solids submitted to large deformations

Main coding languages

• C++: algorithms
• Python: input files

Main features

• 2D/3D elements (large strains).
• Implicit/explicit time integration (HHT, Chung Hulbert, …)
• Thermomechanical coupling (staggered or fully coupled schemes).
• Frictional contact between deformable bodies or analytical surfaces.
• Arbitrary Lagrangian Eulerian formalism.
• Meshing and remeshing procedures.
• Large set of constitutive laws (thermo-elasto-visco-plastic, damage, …)
• Crack propagation (erosion method).

Metafor…

• … is a numerical implementation of the algorithms described in course MECA-0464
• … includes all the PhD theses, Final Year Projects and research projects performed at Prof Ponthot’s laboratory
• … is not a commercial software (less robust but more modular)

Typical applications

• Metal forming processes (roll forming, deep drawing, roll levelling, hydroforming, etc.)
• Crash, impact (fan blade out, shock absorbers, etc.)
• Biomechanics (brain shift, orthodontics, etc.)
