Voidfraction model divided

Hallo,

I have a question about the Voidfraction model divided. In my simulation particles start to rotate when they attach on the edge of a surface. Does this rotation have to do with the divided approach (e.g.. di Felice drag)?

Particles are split into pieces as the documentation said. Does this lead to rotation if a particle is located in two CFD cells? Or are only translational motions calculated?

Thanks for your help. Best wishes,

Johannes
