Hi everyone!
I am trying to prepare a simulation of the NREL 1.5MW reference wind turbine using FLOWUnsteady, but I have encountered some problems when generating the rotor geometry in a specific mode: when I generate the geometry with the option turbine_flag=true, I can generate the blades, but at the root where the cylindrical part is located, the geometry is not generated correctly, as shown in the figure, while the wireframe and the vlm are ok. However, when I generate the geometry with turbine_flag=false, the root part is generated correctly.
Can anyone explain why this happens? I understand that activating the turbine_flag inverts the "twist" value, as seen in the figure, to set the rotor in turbine mode and extract energy, but for the rest, the other splines remain unchanged.
case turbine_flag = true
case turbine_flag = false
