+# 🌀 Navier-Stokes Simulation Dataset (Re=500, T=300)
+
+This dataset contains 300 time steps of a high-resolution 3D Navier-Stokes simulation at Reynolds number 500. The full array was split into three parts to comply with file size limitations on the Hugging Face Hub.
+
+Each file is a `.npy` file in NumPy binary format and contains a contiguous slice along the time dimension.
