Hello everyone.

I am simulating the flow inside a cylindrical drum. I am using VOF multiphase and I would like to ask if I can put some rotation to the drum and simulate the problem as axisymmetric with swirl. I have attached my half geometry with the boundary conditions.

My problem here is that the flow is not axisymmetric because as water leaves the inlet it directs downwards due to gravity so I think I can't simulate it as axisymmetric with swirl. I am right?

As you can see in the picture, my geometry is inclined 3 degrees, so does that mean that I have to set a local coordinate system with the x-axis inclined as well or bt defining the axis boundary my x-axis becomes automatically aligned to the edges?
