Solving heat equation in 2D

The aim of this work is to illustrate, how we can resolve heat equation with the PDE toolbox

the study of the heat equation (Fourier law) is probably one of the most studied in the university. Thermiq 1.0 is an application developed in Matlab 7.3.0 and used to perform simulations of the passage of transitional regime to steady state of a cylindrical stem which has been assumed that heat transfer takes place according to the x direction and is prevented any exchange of heat through the side wall!
