Geometric meaning of heat equation

WebThe basic model for the diffusion of heat is uses the idea that heat spreads randomly in all directions at some rate. The heat equation is a deterministic (non-random), partial differential equation derived from this intuition by averaging over the very large number of par-ticles. This equation can and has traditionally been studied as a WebThe heat equation could have di erent types of boundary conditions at aand b, e.g. u t= u xx; x2[0;1];t>0 u(0;t) = 0; u x(1;t) = 0 has a Dirichlet BC at x= 0 and Neumann BC at x= 1. Modeling context: For the heat equation u t= u xx;these have physical meaning. Recall that uis the temperature and u x is the heat ux.
