Hi all

The simulation is about cutting transport and uses Eulerian model in Comsol. There is two concentric cylinders. The inner one rotates and the outer one is fixed. The fluid flows between these cylinders.
It is possible to be simulated by "rotating shaft" in its mixture model. But due to density differences of fluid-solid, Euler model must be used.
BUT There is no "rotating shaft" or "moving wall" ,as in other models, in Euler model to make a wall rotate. So can anyone who is familiar with Comsol help me on this subject please???

Thank you
