The thermal conductivity is a power-law function of temperature. It is shown that the accuracy of numerical solutions obtained by both the explicit difference scheme and the implicit difference scheme depends on the method for calculating the values of the thermal conductivity coefficient at the nodes of the difference grid. A method is indicated that makes it possible to obtain a numerical solution that is sufficiently close to the analytical solution, including in the zone of the temperature front.</p>
