The document discusses the Ansys Customization Toolkit's Windloading Extension, which is designed to calculate wind loading forces based on wind velocity, air density, and surface area. Key functionalities include assigning pressure in a specific direction, handling constant or gradient loading, and considering shape factors for various profiles. Additionally, the setup process in the Ansys Customization Toolkit (ACT) is outlined, emphasizing the importance of result post-processing for wind speed effects.

- 3. © 2011 ANSYS, Inc. April 15, 2014 3 Description of the Windloading Ext. What should the Capabilities of the extension be: • a pressure should be calculated based on wind velocity; • the pressure should be assigned in a direction; • only positive pressures should be added; • pressure should also be reduced based on the orientation of the element and the loading direction; • 2 loading type: constant or gradient loading across the height of the construction; • a shape factor can be assigned for different types of profiles (code check)
