Flow through an asymmetric plane diffuser

Here you can find all the files to compute the tutorial without using the graphical interface. You will need to work with user subroutines to set up the cases. More information of the case and more results can be found on the test case page here


  1. Knowledge of basic linux/unix commands.
  2. A working installation of Code_Saturne version 2.0rc2.
  3. Paraview and xmgrace installed.
  4. A text editor.

The following file has the step by step tutorial Here you can find the files to run the flow in a diffuser without using the graphical interface.

  • diffuser_tutorial.pdf: Tutorial to compute the flow in a diffuser without the use of the graphical interface.

the tutorial comprises two parts: an inlet periodic channel and the diffuser itself. The corresponding files can be downloaded below:

Periodic channel calculation to obtain inlet conditions:


Experimental results

The experimental results can be downloaded from the ERCOFTAC Workshop in Delft:
