Hi, I would like to implement a source that is time dependent in the heat equation that I model with the pdetoolbox. Typically I am considering a very simple case described below. I consider a c... In mathematics and physics, the heat equation is a certain partial differential equation. Solutions of the heat equation are sometimes known as caloric functions. The theory of the heat equation was first developed by Joseph Fourier in 1822 for the purpose of modeling how a quantity such as heat diffuses … See more In mathematics, if given an open subset U of R and a subinterval I of R, one says that a function u : U × I → R is a solution of the heat equation if where (x1, …, xn, t) … See more Physical interpretation of the equation Informally, the Laplacian operator ∆ gives the difference between the average value of a function in the neighborhood of a point, and its value … See more The following solution technique for the heat equation was proposed by Joseph Fourier in his treatise Théorie analytique de la chaleur, published in 1822. Consider the heat equation for one space variable. This could be used to model heat conduction in a rod. The equation is See more The steady-state heat equation is by definition not dependent on time. In other words, it is assumed conditions exist such that: See more Heat flow in a uniform rod For heat flow, the heat equation follows from the physical laws of conduction of heat and conservation of energy (Cannon 1984). See more In general, the study of heat conduction is based on several principles. Heat flow is a form of energy flow, and as such it is meaningful to speak … See more A fundamental solution, also called a heat kernel, is a solution of the heat equation corresponding to the initial condition of an initial point source of heat at a known position. These can be used to find a general solution of the heat equation over certain domains; … See more
