WebA reference frame is a like a fixed point. Properties of other objects such as: position, velocity etc. are measured using the point. It is so because no point in the universe is stationary or static. Every point is moving depending on another 'so called' static point.

WebIn this section we will use the Multiple Reference Frame method, which is used for the stationary flow solution computation. To simulate the rotation, the real movement of the mesh is substituted by momentum sources in the stationary cells – we add the so called Coriolis term. We need to choose the rotating zone, where we simulate the rotation.
