Welcome to the WInDS wiki!

The Wake Induced Dynamics Simulator (WInDS) is a lifting-line theory (LLT) based free vortex wake method (FVM) code developed at the University of Massachusetts Amherst Wind Energy Center with the express purpose of modeling the offshore floating wind turbine (OFWT) aerodynamics to a higher degree of accuracy than is possible via momentum balance methods.

Download the latest version of WInDS in Fortran here:

Check the sidebar at the right side of this page -->

The instructions to compile FAST-WInDS on Massachusetts Green High Performance Computing Center(MGPHCC) are shown in here. To compile on other Linux/Unix platforms, the user may need to modify makefile according to the configurations.

(Note: Remember to load GCC compiler as well)

Two simple test cases are provided here.
