====== 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.)
