The heat equation models the flow of heat in a rod that is insulated everywhere except at the two ends. Solutions of this equation are functions of two variables -- one spatial variable (position along the rod) and time. The "one-dimensional" in the description of the differential equation refers to the fact that we are considering only one ...

Most of the above mentioned works contribute on linear fractional differential equations and finite difference method combined with ADI technique.
This is code can be used to calculate transient 2D temperature distribution over a square body by fully implicit method.The paper presents a method for boundary value problems of heat conduction that is partly analytical and partly numerical. This is accomplished by changing the differential equation of heat conduction into a differential-difference equation where the space variable is analytical and the time variable discrete. The approach leads to a linear ... 1 day ago · I have to find difference between ADI method on solving 2D diffusion equation with larger time-step and also 2D steady-state diffusion equation using centered difference method with smaller time-step. The boundary is Dirichlet.
