Equation Based Modelling on Comsol for Diffusion Heat Transfer
Many engineering problems are solved by finding the solution of partial differential equations that govern the phenomena. For example, in solid mechanics, the stress distribution can be solved by finding the solution of equilibrium equations in x, y and z coordinates (cartesian coordinate system). Similarly, in heat transfer, the temperature distribution in time and space can be determined by solving the heat diffusion equation. The three-dimensional heat diffusion equation in…
