To change the wind angle in wind analysis using ANSYS FLUENT, you need to modify the boundary condition for the velocity inlet or the wind profile. First, set the wind direction by defining the velocity components (Ux, Uy, and Uz) corresponding to the desired wind angle. This can be done by calculating the components using trigonometric functions (e.g., , , where is the wind angle). Input these components in the boundary condition settings under the velocity inlet. Alternatively, for more advanced wind profiles, use a User-Defined Function (UDF) to specify the angle-dependent velocity distribution. After updating the wind direction, reinitialize the solution or run the simulation to analyze the effects of the modified wind angle.

Thank you Mr. Dewangan . It works

To change the wind angle in wind analysis using ANSYS FLUENT, you can modify the direction of the velocity components in the boundary conditions. First, identify the inlet boundary where the wind velocity is defined. Then, decompose the wind velocity into its components along the Cartesian axes (e.g., X and Y) based on the desired wind angle. You can calculate these components using trigonometric functions: and , where is the wind speed and is the angle of the wind with respect to the reference axis. Update the velocity values in the boundary conditions accordingly. Finally, reinitialize and run the simulation to analyze the effects of the updated wind angle.
