Hello everyone!
I'm trying to simulate air movement in 2D. There is an external fixed cylinder and an internal rotating one, as well as two channels (upper and lower) for air exhaust. The geometry, shaft speed and air mass flow through the shaft are known.
I was unable to simultaneously “apply” the Rotating Wall and Mass Flow Inlet conditions to the inner cylinder (modeled so that air flows evenly, as if from a shaft (inner cylinder)). Is it possible to first set only the shaft revolutions and then use the obtained results as input data for the next simulation, in which the shaft will be specified as “Mass flow Inlet”?
