In the case of heat transport problems in systems having complex structures, it is not always possible to obtain analytical solutions. Besides, sometimes it is difficult to perform thermal measurements. The finite element (FE) method is a  numerical procedure that can be used to simulate heat transport phenomena in such a system. The principle and the structure of software based on FE numerical method are presented. The versatility of the method it is shown by a few examples illustrating the propagation of thermal waves in one and three dimensions and by the analysis of multilayered samples.
