Inflow data play an important role in the numerical simulation of wind loads using large eddy simulation. The inlet generator generates transient inlet data for the efficient modeling of a neutrally stable atmospheric boundary layer. Input parameters determine the statistical description of the numerical wind field such as mean velocity profile, turbulence intensity profile, energy spectrum and length scale. A three-dimensional frozen wind field is generated and saved in an HDF5-formatted file for later use in a numerical wind load simulation. The transformation from the frozen wind field into a transient inflow is realized using Taylor's frozen turbulence hypothesis. The inlet data is interpolated onto the grid points of the LES domain inlet.
