| Combined Eulerian/Lagrangian Approach - • Progresses in High Performance Computing and affordability make Eulerian/Lagrangian approaches economically viable. This approach was first proposed a few decades ago but never really used because of computer limitations that no longer exist. Lagrangian particles, representing Earth's materials, move through a stationary Eulerian mesh. The relevant equations are solved at the nodal points and information such are stress and strain rates are relayed to particles carrying the information through the mesh. Particles are therefore moving integration points that provides the nodes with the information necessary to solve the relevant equations. This approach allows large deformation on rheologically complex models. |  |

| • Open source codes and codes easily accessible (Ellipsis3D, Underworld, SNAC…) offer new opportunities for tectonicists to design better more robust models and from them create new knowledge. |  |
