This data repository contains the OpenFOAM simulation data and results using the wall-modeled large-eddy simulations (WMLES) framework for high-Reynolds-number sheared convective atmospheric boundary layer (ABL). The proposed framework enables accurate and computationally efficient CBL inflow generation for wind farm simulations in modern HPC systems by employing ABL-tailored wall functions along with a non-uniform grid and a TVD scheme, laying the groundwork for future studies involving surface roughness, heterogeneity, terrain complexity, and advanced wall-model formulations.

The dataset contains three main folders corresponding to the simulations on the non-uniform grid using the ABL-tailored wall function, the universal law of the wall, and Reichardt's law. Each folder contains the mandatory folders required to run the OpenFOAM simulations, i.e., "0", "constant", and "system" folders; and also results in "25000" and "postProcessing" folders. The velocity (U), potential temperature (T), the subgrid-scale (SGS) viscosity (nut), thermal diffusivity (alphat), alternative pressure (p_rgh), and turbulent kinetic energy (turbulenceProperties:k) at 25000s simulation-time are located in the "25000" folder. The time-averaged mean of velocity (UPrime2Mean) and turbulent kinetic energy (turbulenceProperties:kMean) are also included. Only for the results with the Reichardt law, an additional file "samplingCells" is included, which indicates the cell-center height from where the velocity data is sampled to calculate the wall shear stress. The temporal evolution of the dimensionless wall distance (z⁺) values throughout the simulation are included in the "postProcessing" folder. Lastly, the *.foam file allows the user to open the case using Paraview. Users interested in viewing the grid can run the blockMesh command. It will generate the grid folder "polyMesh" inside the "constant" folder.
