This paper presents a new algorithm (INNOV) capable of generating a mesh of three-dimensional objects containing multiple phases. This mesh can later be imported into commercial or open-source software to perform multiphysics-based simulations based on partial differential equations. While the range of application is large, this algorithm is designed as a post-processing tool of micro/nanotomography images and electrode mesostructures predicted from CGMD (coarse-grained molecular dynamics) simulations of the electrode fabrication process carried out in LAMMPS software. With INNOV, it becomes possible to import the predicted multiparticle electrode mesostructures into COMSOL Multiphysics in order to simulate electrochemistry and transport in operating lithium-ion batteries.
