[en] This is an outline of a large code for computing superthermal electron transport in laser fusion plasmas. The code involves the computations of mass, momentum, electron temperature, ion temperature, photon temperature, numbers of superthermal electrons and thermal electrons, electric field, etc.. But the numerical methods for superthermal electrons are centrally considered in this paper. Especially the mapping from kinetic energy bins into total energy bins is adopted. The figures of numerical simulation conforming with the experimental results are also presented
