Note as well that is should still satisfy the heat equation and boundary conditions. It won’t satisfy the initial condition however because it is the temperature distribution as t → ∞ t → ∞ whereas the initial ...

Webinhomogeneous boundary condition so instead of being zero on the boundary, u(or @u=@n) will be required to equal a given function on the boundary. The second kind is a \source" or \forcing" term in the equation itself (we usually say \source term" for the heat equation and \forcing term" with the wave equation), so we’d have u t= r2u+ Q(x;t) WebNov 16, 2024 · In this section we take a quick look at solving the heat equation in which the boundary conditions are fixed, non-zero temperature.
