COMSOL Multiphysics was used to solve a phonon Boltzmann transport equation (BTE) for nanoscale heat transport problems. One dimensional steady-state and transient BTE problems were successfully solved based on finite element and discrete ordinate methods for spatial and angular discretizations, respectively, by utilizing the built-in feature of the COMSOL, Coefficient Form of PDE.
