Overview

FEBioChem is an FEBio plugin for modeling reaction–diffusion and reaction–diffusion–convection processes in non-deformable mixtures. It is designed for systems involving multiple interacting chemical species, where transport occurs through diffusion and advection, and species may also participate in complex reaction networks. These species can exist either as mobile solutes carried by the solvent or as solid-bound constituents attached to the mixture matrix. By assuming the mixture is non-deformable, FEBioChem eliminates the need to solve for solid mechanics, leading to simplified formulations, reduced computational cost, and improved performance—while still capturing the essential physics of chemically reactive transport.
