WebOct 13, 2024 · For our model, let’s take Δ x = 1 and α = 2.0. Now we can use Python code to solve this problem numerically to see the temperature everywhere (denoted by i and j) and over time (denoted by k ). Let’s first import all of the necessary libraries, and then set up the boundary and initial conditions. We’ve set up the initial and boundary ... WebThe diffusion number is given as d x = ν Δ t ( Δ x) 2 and for one-dimensional applications the stability criteria is d x ≤ 1 2. The solution presented here is obtained using a diffusion number = 0.5 (CFL = 0.5 in configuration file). Time step size will be computed using the expression of diffusion number. marc o polo taschen
