- The use of computational methods for solving partial differential equations in the field of Heat Transfer is crucial. However, the actual user friendly commercial applications, for the resolution of this kind of problems are expensive. The purpose of this work is the development of a graphical interface for the resolution of heat transfer problems using the finite volume method. This development is made in MATLAB, due to its capacity to generate graphical results in an easy and efficient way. This graphical interface is used as a learning tool in post graduation studies at University of Minho.
