Instantaneous data

Instantaneous volumetric data is provided for 60 evenly-spaced snapshot over the time window with , .

Each wrapped file is denoted with a number which represents the time and contains the instantaneous velocity, pressure and temperature as well as their gradients. The data is provided separately for the inlet square duct area (x=[0,5]) and the diffuser area (x=[5,42.5]).

For more information regarding the storage format, please refer to the storage format guidelines.
