Day 1
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 hangs-on glimpse into the workflow of CFD simulations with OpenFOAM. The following topics will be covered:
- basic case setup
- initial values
- mesh
- simulation (2D elbow case with three meshes)
- postprocessing
Cavity tutorial
This is one of the most basics tutorials. You will revisit this example, so it is a good idea to try it out now. Here, you will get a fast walkthrough with a good explanation about
- the mesh
- running the case
- postprocessing the results.
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.
blockMesh with the cavity case
As already mentioned, we now revisit the cavity case with a special focus on the the OpenFOAM internal simple meshing utility called blockMesh. Study
- the dictionaries (e.g. blockMeshDict)
- mesh your case
- run and postprocess your simulation
blockMesh - advanced
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 focus is on
- scaling the mesh
- setting the vertices
- setting volumes (blocks)
- setting edges
- boundaries
- grading
blockMesh - summary
Yes, the first day is almost over. Look forward to your regeneration by finishing this last tutorial. Here you will find a summary on meshing with blockMesh. You will find a
- visual description of the blockMeshDict dictionary
- fun geometries for exercise
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.
