Layout / Siting
Initial WTG geometry and orientation before terrain flow and final wakes
Installed
Layout / Siting: define the initial turbine geometry before terrain-flow and final wake calculations. The selected layout becomes an immutable upstream input for Wind Flow / Terrain.

WTG layout / coordinates
Recommended WGS84 columns: turbine_id,latitude,longitude. Optional fourth column: ground_elevation_m.
This is the initial siting geometry. Wind Flow / Terrain is calculated only after these coordinates exist. TopFarm2 can later refine positions inside the terrain-transfer atlas.
0 = choose automatically.
Defines the usable terrain-transfer target area. Wind Flow / Terrain will add a separate solver boundary buffer outside it.
Layout summary
Fast wake-screening assumptions
Used only when Row orientation method = Fast PyWake wake-AEP orientation scan. This screening is deliberately separate from the final PyWake wake calculation.

Fast orientation screening — estimated wake AEP
Flat-site screening only. Final wake calculation remains in the PyWake stage.
WTG layout and terrain target boundary
The terrain target boundary is the WTG envelope plus the project margin. Wind Flow / Terrain may add a separate solver buffer outside this area.

Calculation logic / How this works

Create or import the initial turbine layout before Wind Flow / Terrain. This removes layout generation from the final PyWake stage and makes the project area explicit before terrain-flow modelling.

  1. Select a completed Turbine Definition & Gross AEP job and inherit turbine count, rotor diameter, selected real year, power/Ct curves and hub-height wind series.
  2. Either upload/paste WTG coordinates or generate a rectangular/staggered layout around a WGS84 center with explicit D-based spacing.
  3. For auto layouts choose row orientation manually, perpendicular to the dominant wind-frequency sector, perpendicular to the dominant gross-energy sector, or by a fast PyWake wake-AEP scan.
  4. Store the resulting WTG coordinates as an immutable Layout job and define the exact WTG envelope plus a larger terrain target area using the selected project margin.
  5. Pass the layout forward to Wind Flow / Terrain. Real terrain solvers may add their own boundary buffer outside the terrain target area.
Wind/energy-rose orientation is a pre-terrain heuristic. Fast wake screening uses a flat background flow and is not the final PyWake calculation. TopFarm2 later refines coordinates inside the already modelled terrain-transfer atlas.
