Hello everybody,

I want to simulate the behavior of a rheometer with a CFD-DEM solver, the geometry is available on the photograph. Now the internal element (the green one in the photo) is rotating with a certain rotation velocity omega. if I want to simulate it properly i should use a moving mesh, however I do not dispose of such an option and I was asking myself if it would be right to eliminate the internal element and apply to the solid phase and to the gas phase the force normaly exherted by the internal element, i.e. F/rho=omegaX(U), do you think this would do the trick?

thanks to everybody for the attention and the help in advance,
Riccardo
