In this paper, a new numerical method for solving the Stefan problem based on the time function of phase transitions is considered. A nonlinear integral equation of minimal dimension is obtained and an efficient numerical method for solving this equation is proposed. The method is tested on important problems of thawing of frozen soils with various methods of thermal action.
Keywords: Stefan problem, integral equation, numerical method, soil thawing.
