MUST is an in-house development based on OpenFAST [1]. It is designed to allow the simulation of more than one wind turbine (Tower, Rotor, Nacelle) installed on a floating platform, following the work by [2].
MUST has been coupled to a CENER in-house aerodynamic module, AeroVIEW [3], [4] (Aerodynamic Vortex fIlamEnt Wake), that is able to capture the aerodynamic interaction between nearby rotors in aeroelastic simulations and also the interaction between the rotor with its own wake.
