Overview
This asset provides the dataset and reference OpenFOAM configuration to be used for the Datacenter CFD use case here.
The dataset contains normalized OpenFOAM simulations for various configurations of a typical hot aisle in a datacenter. The dataset includes variation for the number of IT racks and hot-aisle geometry parameters like length, height and width of the hot aisle. These configurations are solved with OpenFOAM assuming maximum flow rate and rack exit temperature… See the full description on the dataset page: https://huggingface.co/datasets/nvidia/PhysicsNeMo-Datacenter-CFD.FuXi-CFD-dataset

This dataset is a great choice because it is relatively small in size, yet provides valuable information about aerodynamic simulations. It's ideal for teaching and experimentation, as it won't demand excessive storage or computational power. This dataset is for R&D and demonstration purposes and not meant for production.
