WiTTS is the Wind Turbine and Turbulence Simulator, developed by Dr. Shengbai Xie as part of his Ph.D. under the supervision of Dr. Archer. Features of WiTTS include:

- 4th-order finite-difference or pseudo-spectral incompressible large-eddy simulation (LES) code;

- written in Fortran 77 and MPI parallelized in three directions;

- actuator line model for wind turbines.
