CACTUS (Code for Axial and Cross-flow TUrbine Simulations), developed at Sandia National Laboratories, is a turbine simulation code based on a free wake vortex method.
CACTUS can be compiled via CMake. For details, see doc/compile.md
Simple regression tests are included. After compiling, navigate to test/RegTest/ and run:
PATH=$PATH:../../bin pytest runreg.py
bin: Default target for compiled executablesDAKOTA: DAKOTA drivers (by Jon Murray) and examplesdoc: Documentation -- user's manual, install instructions, DAKOTA drivers manual, relevant publicationsmake: Makefiles for various compilers and platformssrc: Source codetest: Test cases (regression tests, example HAWT/VAWT input files, airfoil files)
Tools for post-processing data from CACTUS simulations are available in the CACTUS-tools repository.

A CACTUS model V&V studies (Michelen et al. 2014, Wosnik et al. 2016) for cross-flow hydrokinetic turbines demonstrated it accurately predicts performance characteristics for axial-flow turbines, but it should not be used for cross-flow geometries.
