FLORIS on GPUs with gradients

FLORAF is the FLORIS wake models and API with support for NVIDIA and Apple GPUs and automatic differentiation. This unlocks running large wind farm studies and gradient-based layout and yaw optimization in a fraction of the time.

100× faster AEP on large farms
GPU NVIDIA (CUDA), Apple (Metal, MPS)
AD Automatic differentiation with PyTorch

The bigger the farm, the bigger the gap

FLORIS runtime grows quickly with turbine count. FLORAF keeps large problems interactive.

Runtime vs. number of turbines

FLORIS (CPU) FLORAF (GPU)

Illustrative data. Lower is better. Both axes are logarithmic.

Optimize with gradients, not guesswork

Automatic differentiation gives exact gradients in one pass, so optimizers reach good layouts and yaw strategies sooner.

Layout optimization

FLORIS (finite differences) FLORAF (gradients)

Illustrative data. AEP gain over the initial layout vs. wall-clock time.

Yaw optimization

FLORIS (finite differences) FLORAF (gradients)

Illustrative data. AEP gain from wake steering vs. wall-clock time.

FLORAF vs. FLORIS

Same wake modeling you trust, built for scale.
