Theory

• Crash In these sildes you will find an in depth summary of the theory of CFD and also OpenFOAM.

Application

• In this tutorial you will find strategies on how to improve your simulation results by optimizing the utilized discretization settings.
• This tutorial gives insight into discretization and the influence of different schemes on the simulation results. The pdf version can be found here.
• Here you will see the influence of the mesh type, hexaeder and tetraeder, the orientation of the mesh and the mesh density on the accuracy of the solution and if the scheme produces physical or also non-physical values.
• Here you will learn the importance of grid resolution and its effect onto your results. The pdf version can be found here.
• Here you will get a basic idea on the structure of the transport equations, which are solved in CFD and also in OpenFOAM. The pdf version can be found here.
