[Other] Sliding Meshes (Version 4 and above)

Tulekk · May 25, 2017, 14:58

OBJECTIVE: Hello community, I am a new to OpenFoam and recently start exploring it so I can use it for part of my dissertation. I am working vertical axis wind turbines and I am trying to figure how I can use sliding meshes in OpenFoam so I can have rotation in my mesh.

QUESTION: Can I work with sliding meshes in the latest versions of OpenFoam?

INFORMATION I GATHER:I read that they disable the function, and so one has to install the "foam extend" in order to use it? What do you know about that? I am asking this because I find it really odd that I cannot find this information anywhere. I just find people telling that they use extend foam to do this kind of work. And if they use open foam, it is a previous version, like around open Foam 2.1.

I TRIED: Anyway, I tried to run the tutorials of pimpleDyMFoam like the propeller with openFoam 4.1 and with the foam extend 4.0 but I couldn't. Maybe works just with a previous version? so maybe the format is different in some files and I have to use the same as older version?

What do you think guys? I really appreciate some help. I could also try with others packages like Fluent or StarCCM. I am exploring right now.

Where did you get the Information that the sliding interfaces are disabled? In the latest version you have AMI and ACMI. The extend offers you another sliding interface (GGI) which can handle more/other things as far as I read but till now I was using the foundation version and everything works well. Even I provide some AMI/ACMI tutorials so actually I know that it is working.
