Instantaneous data
Instantaneous volumetric data is provided for 60 evenly-spaced snapshot over the time window , where , .
Each file is denoted by a suffix which represents the frame number and contains the instantaneous velocity, pressure and temperature as well as their gradients. The data is provided for the region close to the smooth bump and , where <math>x=0<\math> is the bump origin.
For more information regarding the storage format, please refer to the storage format storage format guidelines.
