Go back to Day 4.

Discretization

1D scalar transport

In this tutorial

you will get a detailed introduction into discretization. The order of magnitude of the utilized discretization is as important as your grid resolution. A detailed knowledge on the basics will help you improve your simulations results. This tutorial gives you an understanding on the theory, an introduction on the implementation as well as the application of different schemes within an OpenFOAM case. The topics covered here are:

  • spatial discretization
  • face interpolation
  • changing schemes in OpenFOAM
  • divergence schemes
  • influence of discretization on the simulation results of a passive scalar
  • post processing
