In the wind energy community, the following design codes are commonly used to model and simulate the wind turbine dynamic behavior, as well as to carry out design calculations.

• ADAMS/WT (Automatic Dynamic Analysis of Mechanical Systems - Wind Turbine)

ADAMS/WT is an add-on package for the general-purpose,multibody package ADAMS. ADAMS/WT is developed by Mechanical Dynamics, Inc. (MDI) under contract to the National Renewable Energy Laboratory(NREL), specifically for modeling horizontal-axis wind turbines of different configurations. The ADAMS-code is intended for detailed calculations in the final design stage. Both the subroutine packages AeroDyn (computes the aerodynamic forces for the blades) and YawDyn (blade flap and machine yaw), developed at the University of Utah, can be incorporated in the package. In the 2.0 release, ADAMS/WT is limited to fixed- or free yaw, horizontal-axis wind turbines with two-bladed teetering or 3, 4 or 5-bladed rigid hubs.

• BLADED for Windows - Offshore Upgrade
BLADED for Windows is an integrated software package offering the full range of performance and loading calculations required for the design and certification of both onshore and offshore wind turbines. This code is developed at Garrad Hassan & Partners Ltd., Bristol, England, and has been accepted by Germanischer Lloyd for the calculation of wind turbine loads for design and certification.

• DUWECS (Delft University Wind Energy Convertor Simulation program)
The development of this code started in 1986 at the Mechanical Engineering Systems and Control Group of Delft University of Technology, The Netherlands, in order be able to optimize controlled, flexible horizontal-axis onshore wind turbines. In 1993 DUWECS has been extended to be able to deal with offshore wind turbines. Since 1994, this code is maintained by the Institute for Wind Energy, also from Delft University of Technology.

• FAST (Fatigue, Aerodynamics, Structures, and Turbulence)
The design code FAST has been developed at Oregon State University under contract to the Wind Technology Branch of the National Renewable Energy Laboratory (NREL). There are two versions of FAST, notably, a two-bladed version called FAST-2, and a three bladed version called FAST-3. The FASTcode is intended to obtain loads estimates for intermediate design studies. The number of degrees of freedom is limited in order to reduce runtimes for a wind turbine model simulation. Typical runtimes with FAST-2 take about onesixth the time required for a similar ADAMS/WT run for a similar wind turbine model. In 1996, NREL has modified FAST to use the AeroDyn subroutine package developed at the University of Utah to calculate the aerodynamic forces along the blade. This version has been called FAST-AD.

• FLEX5
The design code FLEX5 has been developed at the Fluid Mechanics Department of the Technical University of Denmark. FLEX5 simulates the dynamic behavior of both onshore and offshore wind turbines wind turbines with 1 to 3 rotor blades, fixed or variable speed, pitch or stall controlled. The aero-elastic model is formulated in the time-domain, and uses a relatively limited number of degrees of freedom to describe rigid body motions and elastic deformations. In the present version FLEX5 is limited to monopile foundations.
