OrcaFlex is a commercial software package developed by Orcina for the design and analysis of marine systems. When the OrcaFlexInterface module is used in [FAST v8] (https://nwtc.nrel.gov/FAST8 "FAST8"), all hydrodynamic and mooring loads will be computed using OrcaFlex, while the turbine, tower, and floating platform structural dynamics; aerodynamics; and control and electrical-drive dynamics will be computed by FAST.
For more information, please refer to documentation on the [OrcaFlex Interface web site] (https://nwtc.nrel.gov/OrcaFlexInterface "OrcaFlexInterface").
You can find libraries needed to compile the FAST 7 version of FASTlink [here] (http://wind.nrel.gov/public/jjonkman/FAST/FASTlinkDLLlib/).
