2D Heat Equation Using Finite Difference Method with Steady-State Solution

This code is designed to solve the heat equation in a 2D plate.Using fixed boundary conditions "Dirichlet Conditions" and initial temperature in all nodes, It can solve until reach steady state with tolerance value selected in the code.After solution, graphical simulation appears to show you how the heat diffuses throughout the plate within time interval selected in the code.you can find in the link below a full report about the code with the results for some cases studied using this code and also how to use it.https://drive.google.com/file/d/0BwE9qaLqIPqSQ1lDTXF6Ry1WT28/view?usp=sharing
