Hello everybody, im trying
 

Hello everybody,

im trying to set up a calculation for a propeller by adapting the mixerVessel2D to a 3D problem.

For my case i generated three cylinders of which the one in the middle should be the rotating.

My Problem now is to define this rotating system in the middle. My thought is to select the cells in the middle with "cellSet" witch saves it so a set called "mixer". After that im not sure what to do cause i need all cells in this set to rotate. I can create the "cellZones" file by shell command "cellsToZones".

Summary: created "cellZones" file with all Cells in the middle clylinder

Now i want to rotate these cells from middle cylinder and add 2 sliding interfaces between the other ones... does anyone have a conlusion for this?

Thx a lot.
