When ELPH_TRANSPORT = True, VASP calculates the transport coefficients from the linearized Boltzmann transport equation. In this framework, the transport coefficients are calculated from various relaxation-time approximations selectable via ELPH_SCATTERING_APPROX. A convenient way to start transport calculations is to set ELPH_MODE = transport, which automatically provides reasonable default values for the required INCAR tags.
