Hello everybody,

I work on an external aerodynamic case with openFoam. I constructed my case like motorbike tutorial, I have a .stl file with one element. I created a domain with blockMesh, and after I included the stl and refined my mesh with snappyHexmesh. After this first step, I ran my case with simpleFoam, next with pimpleFoam and know I would like to run my case with pimpleDyMFoam.
In dynamicMeshDict I chose solidBodyMotionFvMesh with oscillatingRotatingMotion. To run my case I need a cellZone. My problem is here.

I created a cellzone with toposet but all the domain was rotating and not only the stl.
After I tried to create cellzones with snappyHexMesh but I don't understand how it works.

So my question is: do someone knows how to create a cellzone to move only my stl and not all domain?

Thanks in advance for your help.
