Solving 2-D heat conduction equation both steady state and transient

Objective: A 2-D heat conduction equation is `((del(T))/(del(t)))+alpha*(nabla^2T)=0` which is a partial differential equation. It falls under the category of parabolic pde type. To solve this PDE we are utilising the power of numerical techniques, by using finite difference equations we convert this equation into algebraic equation…
