W artykule przedstawiono numeryczną analizę nieustalonego pola temperatury w trójwymiarowym modelu elektrycznego grzejnika podłogowego. Sformułowano odpowiednie zagadnienie brzegowo-początkowe, które dyskretyzowano niejawną metodą różnic skończonych. Otrzymane układy równań rozwiązano przy wykorzystaniu metody BiCGStab i procesora GPU. Dodatkowe zastosowanie procesora GPU pozwoliło ponad 5-krotnie skrócić czas obliczeń w stosunku do programu pracującego tylko na procesorze CPU.

This paper presents the numerical analysis of the transient temperature field in a three-dimensional model of an electric floor heater. An appropriate initial-boundary value problem was formulated, which was discretised using the implicit finite difference method. Obtained systems of equations were solved using the BiCGStab method and the GPU. The additional application of the GPU reduced the time of computations over 5 times compared to the program executed only on the CPU.
