Feel++ for Multiphysics Modeling and Simulation Toolboxes 1. Core Manuals The Toolbox Core Manuals describe (i) what is a toolbox (ii) how to setup simulation models thanks to JSON files and (iii) configure command line options of the toolboxes Coefficient Form PDEs A coefficient form PDE toolbox to solve N coupled nonlinear PDEs Computational Fluid Mechanics The computation fluid mechanics solves from low to high Reynolds number flows and includes some turbulence models. Computational Solid Mechanics A toolbox to solve non-linear elasticity problems that supports (i) Large deformations, (ii) large displacements; (iv) Compressible, nearly incompressible materials and (v) Multi-material Electric A Toolbox that solves Gauss's Law equation and compute the electric potential and field of a given charge distribution. Fluid Structure Interaction A toolbox for solving fluid-structure interaction problems using ALE formulation and staggered schemes such as Diriexlet-Neumann, Generalized Robin-Neumann, and Robin-Robin. Heat and Fluid A toolbox that solves the heat and fluid equations including convection, conduction effects. it is mostly used for aerothermal problems. Heat Transfer A toolbox to solve heat transfer problems including conduction, convection and black body radiation including non-linear problems and temperature dependent properties. Hybridized Discontinuous Galerkin Toolbox Hybridized Discontinuous Galerkin Toolbox case studies, supporting elliptic and parabolic problems in 2D and 3D including advection, diffusion and reaction, elasticity, Stokes and coupled problems. Maxwell A toolbox for the simulation of electromagnetic fields in 3D including static, low frequency, and high frequency applications and non-linear materials. Multifluid Flow Toolbox A toolbox to solve multuid flow problems using the level set method Thermo-Electric A toolbox to solve the heat equation coupled to the electric currents equation including temperature-dependent material properties.
