sumit_vjti New Member sumit Join Date: Apr 2021 Posts: 2 Rep Power: 0	I am working on savonius turbine which is a Vertical Axis Wind turbine. I have used dynamic mesh method for this. I am getting constant rpm after some iteration and moment is in cyclic variation(fig attached below). I want to know why I am getting -ve moment values ,while rotor is rotating in anticlockwise direction in the entire simulation.
