Hi,
I've tried to set up a dam break problem with the use of adaptive mesh refinement by adding dynamicMeshDict to the constant directory, however no mesh refinement was obtained.

I followed these two guides, which were done for the version v2012, and it seems that the same techniques don't work for v2212.

For the basis I took directory from the first video and changed there some files and keywords to make it runnable for the newer version of OpenFOAM: renamed turbulenceProperties to momentumTransport in constant folder, also changed keyword for writeControl from adjustable to adjustableRunTime. After these manipulations simulation ran successfully, but without any refinement.

Pls, excuse me if my problem is quite obvious, but I'm new to OpenFOAM and have been trying for two days to find the solution with no luck.

Hello,

Not sure about your problem, but you seem to be mixing up OpenFOAM branches and versions.

There are 2 mains branches:

• openfoam.com (developed by ESI-OpenCFD): OpenFOAM-v2012 is the version released in December 2020, v2212 is the version released in December 2022 (the latest one to this day)
• openfoam.org (developed by the OpenFOAM foundation) : OpenFOAM-10 is the version released in July 2022 (the latest one to this day)

So which version are you using? turbulenceProperties file is still used in the ESI-OpenCFD branch while the OpenFOAM foundation branch switched from turbulenceProperties to momentumTransport a while ago.

You should find which version you are using by checking the log files of your case or by typing foamVersion in your terminal.

Regards,
Yann

Thank you for your reply, I've checked this out: my version is OpenFOAM-10 provided by openfoam.org.

I have also OpenFOAM v2212 installed on the WSL (OpenFOAM-10 is installed in VM, I didn't notice I had installed different versions), so I'll check if AMR works there.

Edit: using v2212 instead of -10 solved the problem. Thanks a lot!)
