# Analytics & Performance

After your simulation has been completed, you will be able to access some analytics and performance metrics and visualizations for the met masts and turbines in your simulation domain. This enables a quick triage of the results before a deeper analysis or comparison is done. The plots are generated for each height at the met mast or at hub height at the turbine location.

{% hint style="info" %}
For windturbines the rotor-averaged-windspeed is used to generate the weibull and windrose plots. For more information, you can check the parametrization of the windturbine in the Whiffle LES.

## Performance <a href="#analytics-and-performance-performance" id="analytics-and-performance-performance"></a>

On the performance tab you can inspect the mean wind speed and energy production numbers of all turbines. These numbers are computed for both the simulation period as well as a long-term corrected variant in case more than 180 simulation days are selected. More information about the long-term correction can be found [here](broken://pages/yktDzgzhpl7TPOyF7cij).
