Hi lordvon,

hehe, when have you had this correspondance?

You might be generally better off with OpenFOAM-ext when dealing with dynamic mesh handling... Please have a look:

• PhD Course at Chalmers: http://www.tfd.chalmers.se/~hani/kur...ngTutorial.pdf or lately http://www.tfd.chalmers.se/~hani/kur..._Corrected.pdf
• OpenFOAM-Wiki (which is rather old): http://openfoamwiki.net/index.php/Ho...mic_mesh_cases
• Some newer presentation and papers on that topic (unsorted):
  • Dynamic Mesh Handling in OpenFOAM (1)
  • Dynamic Mesh Handling in OpenFOAM (2)
  • Dynamic Mesh Handling in OpenFOAM (3)
  There might be much more; I have just used my favorite web search engine, briefly searching for "mixerFvMesh" and "OpenFOAM"...

Have a closer look into the tutorial cases of the icoDyMFoam solver: mixer2D and mixerGGI. Further this case is useful, which is a simple extrusion to 3d.

best,
