WebWe will use an FTCS approximation of \[\frac{\partial T}{\partial t}=k\frac{\partial^2 T}{\partial x^2}\] to calculate the evolution of temperature in a rod of length 1. The initial temperature of the rod will be set at 100 but the ends of the rod will be kept constant at 0. The heat conductivity will be set at \(k=0.01\).

The Explicit Forward Time Centered Space (FTCS) Difference …
WebFTCS scheme. Forward Time Centred Space (FTCS) scheme is a method of solving heat equation (or in general parabolic PDEs). In this scheme, we approximate the spatial derivatives at the current time step and the time derivative between current and new time step: t = t 0 + n Δ t, x = x 0 + i Δ x, ∂ u ∂ t ≈ u i n + 1 − u i n Δ t, ∂ u ... WebMay 11, 2024 · The FTCS method comes from the discretization of a diffusion PDE like this: a 2 u i + 1 k − 2 u i k + u i − 1 k Δ x 2 = u i k + 1 − u i k Δ t. If I have the FTCS method in the Finite difference method: u i k + 1 = r ( u i + 1 k + u i − 1 k) + ( 1 − 2 r) u i k with r = a 2 Δ t Δ x 2. It's stability condition is: r = a 2 Δ t Δ x 2 ... rugs hamilton nz
