Hello, I am trying to use simscale incompressible CFD to model flow through a rotating straight pipe (the axis of rotation is perpendicular to the direction of the pipe). I am unsure how to do this with MRF, as all of the examples of rotating geometries that I have seen on simscale use external meshes with boundary conditions that exist outside the rotation zone. In my case, I want a velocity inlet, pressure outlet condition on the pipe itself, which should be rotating at some angular velocity. I am only interested in the flow inside the pipe.
Here is type of rotation I am looking for.
Any suggestions would be hugely appreciated.
