Exporting to WindSim

The WindSim tab of the Export Data window exports two types of data files that you can import into the wind flow model WindSim: WWS files, which contain a table of frequency versus speed and direction, and TWS files, which contain time series data.

Tip: This tab will appear in the Export Data window only if your data set contains speed and direction data, and you are using the Standard or higher edition of Windographer. Please visit www.windographer.com for information on the pricing and capability of each edition.

A WWS file is similar to a TAB file in that it contains a table of frequency versus wind speed and direction sector. But the WWS file has a specific header format and contains fractional frequency values rather than per mille values. The WindSim documentation provides detailed information about the format of WWS files.

When exporting a WWS file, you can choose the number of direction sectors, the speed and direction sensors on which to base the bins, and whether to include all time steps or just a subset of the time steps in the dataset.

A TWS file contains time series data for one wind speed sensor and one wind direction sensor. If your dataset contains multiple wind speed or direction sensors, you can choose the ones to export. You can also choose to export all or just a subset of the time steps in the dataset. You can also indicate the version of WindSim into which you intend to import the data file.

Note that Windographer can open TWS files as well.
