 This file contains metadata related to the simulation, including input parameters such as `wind_speed`, `rotate_angle`, `num_iterations`, and `resolution`. Additionally, it includes output parameters like `drag_coefficient`, `moment_coefficient`, `lift_coefficient`, `front_lift_coefficient`, and `rear_lift_coefficient`. The file also specifies the locations of the generated output meshes.
