Abstract: A numerical method for solving three-temperature equations of radiation viadomain decomposition is presented. The method is based on dividing the domain into two or several domains and solving either three -temperature equations or single-temperature euqation in each domain. Also we present a scheme coupling interface flux between one domain and the next and analyse the convergence of the iteration method for solving the difference equations.
