Hello all,

I am trying to model a rotary tube reactor, where I am trying to model two phase gas-solid flow inside a rotating domain. I am using Euler-Euler for the two-phase flow and I have added a rotating wall to prescribe the rotary motion of the external wall.

A part of the geometry is as shown in one of the images. I want to rotate the outer wall and solve for the flow in the domain highlighted in blue. However, the Euler-Euler interface's wall setting does not include a place to enter or couple directly from frame the rotational component. Only the translational and sliding components are present.

Does anyone know why this is happening? Am I missing something or is there any other way to solve this?

Thanks!
