DynamicMesh OpenFOAM Tutorial 1 - Advanced BlockMesh

Here is my first OpenFOAM video tutorial of the DynamicMesh series.

An advanced use of BlockMesh is shown in order to build a 2D mesh around a NACA0012. This puts the base for the next videos, where I will explain different dynamicMesh possibilities for simulating an oscillating aerofoil.

Constructive comments and suggestions are welcomed.

Hi,

I am trying to use your case in OpenFOAM 10 but some errors appearch due to the Macro Expansion when defining the cylinder. Have you ever tried to run in OpenFOAM v10?

Hi Sir @Sebastian Stipa

I run the blockMesh, and it shows

--> FOAM FATAL IO ERROR: Illegal dictionary entry or environment variable name ":aerofoil.xUpper" Valid dictionary entries are 1(type)

After google-ing, it seems something to do with syntax between old version OF, to the latest.
FYI, currently I use OF9.

Kindly advise. Please.

Thanks

Firstly, I have just noticed your channel by chance, and I kindly surprised about detail of your work. I have checked your previous studies and I wonder are you planning to do a tutorial about wind turbine detaily?

nice video, but i couldn't hear anything until i maxed the volume :p

Thanks for your great Explanation.
I have tried to set up the mesh with my own airfoil. The problem that I have got that I cannot choose a type empty for front and back as my airfoil is not symmetrical. I must choose a type wall.
Due to this i get bad results.
Do you know the reason i cannot choose type empty ?

Hello, Thank you for your video! I would like to do the same but for a NACA0018. Where can i find the NACA0012.obj file but for the NACA0018? I tried to create it with solidworks but the code do no recognize the shaoe of the airfoil and so the mesh is not good. Thank you

Nice Explanation!
Will you please provide the Case files of OpenFOAM....it will be easy for us to learn and practice.
