"3 weeks" series
In this series you will have the possibility to get a more detailed understanding of the basics of OpenFOAM. You will be able to complete it in about three weeks. It is understandable, that you are exited. Everybody is, but please do not work on the weekends. Breaks are important for the learning process. This is the reason, why the tutorials are divided into fifteen days. Do not skip the weekends! Some time without OpenFOAM is also important.
Go back to Tutorials.
In order to be able to complete the tutorials, you will have to install OpenFOAM. There are multiple ways to do this. First, follow the official guideline here.
On Day 1 you will start to get familiar with OpenFOAM. Just follow the instructions step by step and familiarize yourself with the concept of OpenFOAM, Linux, the terminal and working with dictionaries.
- basic workflow in OpenFOAM
- getting used to the terminal
- meshing with the OpenFOAM internal meshing utility blockMesh
- running simulations
- first steps with postprocessing in Paraview
On Day 2 you will continue with your first steps. You will get an even deeper understanding and learn the work flow of OpenFOAM with a special focus on visualization of results.
- more detailed understanding of the work flow
- further short and fun simulations
- grid convergence
- transport equations
- detailed scientific visualization of results
On Day 3 you will digest all the information from the previous days by listening to a talk on the basics of OpenFOAM.
On Day 4 you will understand the theory behind OpenFOAM by taking a detailed look at the discretization of the equations and the numerical settings. We will cover a big theoretical area about
- gradient scheme
- gradient limiter
- convection discretization
- face interpolation
- diffusion discretization
- influence of discretization on the simulation results
- CFL number
- linear solvers
- solution methods
Day 5 is there to round off the week with some fun simulations. Also we give you links to some interesting documents, which can help you solve your problems in OpenFOAM in the future.
Day 6 is all about meshing. In order to be able to run simulation for real life problems, you have to understand how to create an arbitrary high quality mesh and which alternatives you have in OpenFOAM. For this you will learn about
- geometry creation
- mesh generation
