Solving inhomogeneous heat equation Ask Question Asked 4 years, 3 months ago Active 4 years, 3 months ago Viewed 3k times 1 Solve the inhomogeneous heat equation u t = c 2 u x x + sin ( 5 π x) for all 0 < x < 1, t > 0 subject to homogeneous Dirichlet boundary conditions u ( t, 0) = u ( t, 1) = 0 and initial condition u ( 0, x) = 4 sin

The steady-state heat equation is by definition not dependent on time. In other words, it is assumed conditions exist such that: This condition depends on the time constant and the amount of time passed since boundary conditions have been imposed. Thus, the condition is fulfilled in situations in which the time equilibrium constant is fast enough that the more complex time-dependent heat equation can be a…

the variation of parameters for the inhomogeneous equation. The case of the Neumann boundary conditions for the inhomogeneous heat equation is similar, with the only di erence that one looks for a series solution in terms of cosines, rather than the sine series (2). The boundary value problem for the inhomogeneous wave equation, (u tt c2u

Inhomogeneous Heat Equation on Square Domain Copy Command This example shows how to solve the heat equation with a source term. The basic heat equation with a unit source term is ∂ u ∂ t - Δ u = 1 This equation is solved on a square domain with a discontinuous initial condition and zero temperatures on the boundaries.
