The tutorial files are here: https://develop.openfoam.com/Develop...Hill/transient


The first error I get is the following:

wrong token type - expected string, found on line 17 the word 'turbulenceModelSchemes'

-> that's in the controlDict. I get other errors when I try different things to fix that one (well, one error, tried one thing), but they're shots in the dark. Eventually, maybe in a month or two, I'll figure out what the problem is and be able to provide the correction. I figure this post is justified, "official" tutorials are supposed to work.. maybe this one was created for a different version of openFoam? I'm using openFoam 9.

Hi Michael,

There are different forks and development branches in OpenFOAM. Here are the 2 main branches :

• OpenFOAM foundation (openfoam.org) : current version is OpenFOAM 9. OpenFOAM 10 should be released in July
• ESI-OpenCFD (openfoam.com) : current version is v2112, the next version should be released this month (v2206)

For a more complete view of the OpenFOAM world, you can have a look on this scheme, made by Pablo Higuera in 2016: https://olaflow.github.io/images/blo...hoopenfoam.png
It starts to be a bit outdated but it is still interesting to have the full picture.

Now back to your issue: you are trying to run a tutorial from the OpenCFD branch, OpenFOAM-v2112, on Openfoam-9, which is the OpenFOAM foundation branch. Those 2 branches has been forked 6 years ago and the code has been diverging ever since. Both versions have a common heritage but use different syntax, models, solvers,...
This leads to what you are experiencing: you will most probably get a lot of errors if you try running a tutorial from one branch on another branch.

You can adapt some tutorials to the other version, but it can be a hassle to do, especially if you are not very experienced with OpenFOAM. My advice would be to stick to the tutorials available with your version, or to install the proper version if you really need to run this specific tutorial.

On a side note: pay attention to use the documentation corresponding to the version you are using. The documentation on openfoam.com will not be relevant for OpenFOAM-9! This could save you a lot of time and trouble!

I hope this helps,
Yann

..yes indeed, a very valuable response. ..as my old cs-teacher would say: "..you made a lot of millage with that question.."
