Abstract: Solving the differential equation of heat conduction the temperature in each point of the body can be determined. However, in the case of bodies with boundary surface of sophisticated geometry no analytical method can be used. In this case the use of numerical methods becomes necessary. The finite element method is based on the integral equation of the heat conduction. This is obtai-ned from the differential equation using variational calculus. The temperature values will be calculated on the finite elements. Then, based on these partial solutions, the solution for the entire volume will be determined. Using this method we can divide into elements also fields with any border. Also, numerical modelling with boundary elements is used for analysis of heat conduction. In this paper are developed basic ideas of numerical analysis with finite elements and boundary (constant) elements of conductive thermal fields generated or induced into solid body in steady state regime!
. The temperature distribution in some solid bodies and in pipe insulation is analyzed using analytical method and finite element and boundary element methods, implemented in two computer programs developed by the author. This shows the good performance of the proposed numerical models.
