Finite difference heat transfer analyses in Excel In this post I’m tackling something I’ve been wanting to do for some time now. That is setting up and solving a simple heat transfer problem using the finite difference (FDM) in MS Excel. AIM : SOLVING THE STEADY AND UNSTEADY 2D HEAT CONDUCTION PROBLEM. OBJECTIVE: 1. To solve the Heat conduction equation using a Transient(unsteady state) solver and a Steady state solver using Iterative techniques (Jacobi,Gauss Seidal,SOR) 2. Assuming the domain to be a unit square. 3. A finite‐difference method is presented for solving three‐dimensional transient heat conduction problems. The method is a modification of the method of Douglas and Rachford which achieves the higher‐order accuracy of a Crank‐Nicholson formulation while preserving the advantages of the Douglas‐Rachford method: unconditional stability and simplicity of solving the equations at each time level. .
I'm currently developing a program to solve 2D transient state heat conduction on a square plate using the V-cycle multigrid. Althought my program is able to reach the steady state solution, it's computational time is longer then just running the problem using Gauss-seidel method. Problem case: 0.1 m by 0.1 m square plate with fixed temperatures.
chip. Sometimes heat input is more properly modeled as volumetric heat generation in some limited region. In either case, the steepest thermal gradients will occur predictably in immediate proximity to the surface or region of heat inputs.

The finite difference method relies on discretizing a function on a grid. To use a finite difference method to approximate the solution to a problem, one must first discretize the problem's domain. This is usually done by dividing the domain into a uniform grid (see image to the right). FD2D_HEAT_STEADY is available in a C version and a C++ version and a FORTRAN90 version and a MATLAB version and a Python version. Related Data and Programs: FD1D_HEAT_STEADY , a MATLAB program which uses the finite difference method to solve the 1D Time Independent Heat Equations.
