Go back to "3 weeks" series.

Open source geometry creation

Here you will get a detailed introduction into two alternatives for the creation of geometries as inputs for a CFD project in OpenFOAM

  • Salome
  • Onshape

Cavity - revision

Yesterday you already completed this tutorial several times. Here you will be taken into the depth of an OpenFOAM case in order to understand all the important in- and outputs required for a CFD simulation in OpenFOAM.

  • details on OpenFOAM directory organization
  • directory structure of an application/utility
  • applications/utilities in OpenFOAM
  • directory structure of an OpenFOAM case
  • simulation workflow
  • details on the in- and output of an OpenFOAM case

Grid convergence

By now, you should be familiar to the basics of OpenFOAM. Let us continue with some general CFD topics, still covered in OpenFOAM. In this video you will learn the importance of grid resolution and its effect onto your results.

  • field initialization with setFields
  • mesh refinement with blockMesh
  • simulation of a 1D shock tube case
  • influence of mesh refinement on the simulation results
  • postprocessing

Transport equation

Here you will get a basic idea on the structure of the equations, which are solved in CFD.

  • the solver
  • case setup
  • transport phenomena like convection and diffusion
  • influence of constants
  • simulation of scalar transport
  • post processing


In this tutorial you will try a simple simulation with the your newly acquired knowledge on CFD in OpenFOAM.

Visualization 1

In this tutorial you will get a deep understanding on the scientific postprocessing and visualization of results in Paraview.

The following topics will be covered:

  • Postprocessing
  • ParaView in a nutshell
  • ParaView vs. paraFoam
  • ParaView GUI overview
  • Basic usage – Sources and filters
  • Scientific visualization with paraFoam/ParaView

Visualization 2

In this video you will get a summary of scientific visualization of results i Paraview.

Case details

Here you will get a summary of the case setup in OpenFOAM.
