This article will teach you how you can upload a STAT file as wind data for a pedestrian wind comfort (PWC) analysis in SimScale.
A pedestrian wind comfort (PWC) analysis needs the wind data of the interested area to evaluate the pedestrian comfort according to different criteria. You can use the wind data that is provided by SimScale’s partner meteoblue® or you can upload your own wind data into the platform.
STAT File Preparation
To upload the wind data, the file would need to have a .stat file extension. This file contains the wind directions and the proportion of each prevailing wind speed interval. Figure 1 is an example of a .stat file that is ready for upload:
From Figure 1, we can see that the wind directions have an interval of 22.5° and also see the wind speeds which mostly have an interval of 2 \(m/s\). In creating this file, a naming convention will also need to be followed, so that the file can be read properly. The prevailing wind direction consists of just letters. For example, NNE means North North East which is the wind coming from a (22.5° angle) and followed by the angle in parentheses.
The wind speed interval will need to start with a <= symbol which means less or equal than. For example, the second column is <=.5 which means this column contains the proportion of wind speed that is less or equal than 0.5 \(m/s\) for each wind direction. The total proportion of each wind speed interval and the total proportion of wind coming from each direction is also necessary.
STAT File Upload
After the file is ready, it can be uploaded to the SimScale platform as follows:
- Click on ‘Browse files‘ to chose the file containing the wind data
- After you have chosen the file for upload, the wind rose according to your data should appear, like in the figure below:
After this, you are ready to move on to the next steps of your simulation setup.
