Anason tutorial - Particle Dispersion in a Turbulent Pipe Flow - example files

[stichko]

Hello,

I am setting up a simulation model as described in the provided CS tutorial "Particle Dispersion in a Turbulent Pipe Flow - Arnason test case". According to the tutorial text the parabolic velocity inlet boundary condition must be defined through the file "cs_user_boundary_conditions.f90". A customized version of this file, already adapted/modified for this tutorial, should be available according to the text of this tutorial. Where can I find this file? It is not included in the examples folder of the downloaded CS-tar file. I am not a CS and Fortran expert (yet), so this would help me to complete the set-up of this model and run the simulation.

Many thanks for any help!

I'm Trying to run this example using code_saturne 5.0 getting the following error:

Hello,

Which version of MED are you using ? Your library is probably too old compared to the one used to write the mesh.
If you are using Salome for the prerequisites, version 8.5 (with MED 3.3) should be OK.

Also, with Salome 9.2, you can import the mesh an export it in the older 3.2 version, if you just want to modify the mes hand not reinstall.

Best regards,

Yvan

I'm not using salome for the moment, I'd run the tutorial using the mesh file attached in this post, I thought it was fine to use it.
So if I got it, is the code_saturne 5.0 that requires an older version of MED? Is available a mesh for the tutorial?

[Yvan Fournier]

Hello

No, you can compile Code_Saturne 5.0 with any version of MED from 3.1 to 4.0, but you need to update your MED library and reinstall the code.

Attached is a version converted back to MED 3.2 format (using Salome 4; I have not tested this feature before).

Best regards,

Yvan

Thank you very much

It worked, then I compared the flow results with the a different mesh, in the meantime Igenerated with Gmsh and I got comparable results.
Now I would run the two-phase flow using the mesh I generated by Gmsh.
I guess I have to group the cells along the Z axis in a set named "injection".
Is that right?

I run the windows binary downloaded from the download section of the site https://www.code-saturne.org/cms/Production-version-50.

I cannot find in the doxygen documentation reference to the

Code: Select all

cs_user_lagr_volume_conditions

and reference to the function

Code: Select all

cs_user_lagr_in

seems to be not phased.
