As seen on figure below, 2D steady heat conduction with heat source is going to be modeled on a rectangular domain by FVM using matlab programing language. Grid size and size of domain and boundary conditions are going to be input to the problem. For example left side of the domain can be modeled as heat-flux boundary conditions (in or out) and north side may be modeled as constant temperature boundary condition. Right side can be insulated and South side may be assumed heat loss boundary condition defined with a surrounding fluid temperature and heat transfer coefficient "h". An also assume that domain have small amount of heat generation. Total number of control volumes should be around 100-300. Plot the temperature contours.
