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.

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 - basics

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
