3. Output files

3.1 WindSim files

ParkDesign automatically generates the following files, saved to the Results Directory (as defined in Initialisation and General Function):

• energymap.csv — written after the Energy Map is calculated. Can be loaded instead of recalculating the energy.
• .\OPT_OUT\energy_curve.csv — the energy curve E(n) in MWh/year as a function of the number of turbines n. Created when the Layout is optimized.
• .\OPT_OUT\layoutxxx.txt/ows — the turbine layouts corresponding to energy_curve.csv. Formats are WindPro (.txt) and WindSim (.ows).
• .\OPT_OUT\wake_effect_adjusted — directory created when the Layout is adjusted for wake effect.
• energymap_ge.kml and windmap_ge.kml — for viewing in Google Earth.
• parkdesign_gui_vars.mat — the GUI state, saved when the GUI is closed. Can be reloaded with Load Session.

In addition there are temporary files energy.csv (Energy Map), constraints.csv (Exclusion areas) and forbidden.csv (points outside the planning area but within the defined rectangular project grid), used during layout optimization. These are written to the results directory and may be useful for import to other software. ParkOptimizer also uses .pgn (text) files for the Park Area or additional constraints drawn with the editor; saved constraints are stored in csv and Surfer-grid format.

3.2 Other files

Turbine specification file (.pws), defining the power-curve PC, thrust-coefficient Ct functions, and noise curves. ParkOptimizer version > 2.3 can read both the old .pws format (no noise data) and the new format (with noise data).

Wind measurement file (.tws), for optional turbulence and extreme wind in the IEC Constraints calculation.
