Day 1 is all about fast and fun simulations with the focus on
- the 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
Go back to "3 weeks" series.
Contents
First simulation
In this tutorial you will get a first hands-on glimpse into the workflow of CFD simulations with OpenFOAM. The pdf version can be found here. The following topics will be covered:
- basic case setup
- initial values
- mesh
- simulation (2D elbow case with three meshes)
- postprocessing
Basic case setup
Using icoFoam solver, simulate 75 s of flow in an elbow.
- Basic case setup in OpenFOAM
- Setting up initial values of p and U
- Ensuring proper boundary definitions
OpenFOAM basics
Here you will find a video on the very basics of OpenFOAM. You will hear about
- OpenFOAM and what it is good for
- the history and philosophy behind it
- the basics and the structure.
Session A: Getting to know OpenFOAM
In this tutorial you will study
- what is the history of OpenFOAM
- the philosophy behind the OpenFOAM software
- what is the content of the OpenFOAM software package
blockMesh with a more complicated case
In this second tutorial video you will try out your knowledge about blockMesh in order to create a more complicated mesh for a simulation. The pdf version can be found here. The focus is on
- scaling the mesh
- setting the vertices
- setting volumes (blocks)
- setting edges
- boundaries
- grading
Cavity - Revisited
Before you already completed this tutorial a few 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
End of Day 1
Thank you for finishing the first day. We hope, that you had fun and you will continue tomorrow with Day 2. The topics tomorrow are:
- more detailed understanding of the work flow
- further short and fun simulations
- grid convergence
- transport equations
- detailed scientific visualization of results
Homework: relax.
