• Class Summary
Class Description
ConvectionDiffusionEquation1D
The convection–diffusion equation is a combination of the diffusion and convection (advection) equations, and describes physical phenomena where particles, energy, or other physical quantities are transferred inside a physical system due to two processes: diffusion and convection.
CrankNicolsonConvectionDiffusionEquation1D
This class uses the Crank-Nicolson scheme to obtain a numerical solution of a one-dimensional convection-diffusion PDE.
CrankNicolsonConvectionDiffusionEquation1D.Coefficients
Gets the coefficients of a discretized 1D convection-diffusion equation for each time step.
