SofaMJEDFEM plugin for visco-hyperelastic model

Description

This plugin implements the Multiplicative Jacobian Energy Decomposition or MJED method. This discretization method is an alternative to the classical Galerkin FEM formulation. This method for discretizing non-linear hyperelastic materials on linear tetrahedral meshes leads to faster stiffness matrix assembly for a large variety of isotropic and anisotropic materials.
