Below is a list of links to OrcaFlex example topics. Within each topic are a number of examples which each comprise one or more simulation files, a description pdf file, workspace files and sometimes other supporting files. The files for each example are zipped for easy download. The simulation files can be opened and viewed with the demonstration version of OrcaFlex.
This example models the NREL 5MW baseline turbine atop the OC3 Hywind spar. This mock turbine system is recognised as an industry-standard reference model that is representative of a typical utility-scale, multi-megawatt wind turbine. The model itself utilises the turbine object, which we introduced in OrcaFlex version 10.3.
User defined results (UDRs) are also featured in this example. UDRs and the turbine controllers used in this example use the Python API.
This example models the 10MW reference wind turbine (RWT), developed as part of the International Energy Agency's (IEA) Wind Task 37. This turbine is a fixed-bottom monopile design, which uses a system of linear springs to model the monopile to soil interaction.
Control system modelling for the turbine is supported through Python external functions. The turbine controller source code is compiled as a dynamic link library (DLL) which represents NREL's Reference Open Source Controller (ROSCO).
Also demonstrated is the application of a turbulent wind flow using a TurbSim .bts file.
This example models the 15MW reference wind turbine (RWT), developed as part of the International Energy Agency's (IEA) Wind Task 37. The nacelle is supported by the tower which is mounted upon the University of Maine (UMaine) VolturnUS-S reference semi-submersible platform.
Control system modelling for the turbine is supported through Python external functions.The turbine controller source code is compiled as a dynamic link library (DLL) which represents NREL''s Reference Open Source Controller (ROSCO).
