Hi all, I want to run an k-epsilon turbulence model simulation with Code_Saturne 5.0.7, windows version. The mesh that I use for simulation is made using ICEM CFD. The mesh file si saved as CGNS, version 3.1 ADF. In the past I use the same CGNS file type having no error. Now when I use the mesh, the...

Hi, Can someone guide me where to find the theory for turbulence modelling for the k-omega SST turbulence model? I could not find it in the theory manual from Code_Saturne. I am interested on how is computed the production of turbulence and what conditions are applied to it. Thanks in advance, Ionut

Thank you very much Yvan!

Best regards,

Ionut

Hi all! After some searching on this forum and the functions from code_saturne, I found that norm.residual is the residual I should check in order to see if the simulation is converging or not. From the file ecrlis.f90 , the drift or derive residual is defined as DRIFT=((x_n-x_(n-1) )^2*cell volume...

Hi Yvan, thank you for helping me. I made another simulation in Code_Saturne using the k-omega SST turbulence model, ensuring that the no wall function it was selected, my mesh y+ is smaller than 1. The mesh generation I made in ICEM CFD. If I process the results in ParaView the velocity at the wall...

Hello, I made a steady state simulation using the k-omega SST turbulence model on an asymmetric diffuser geometry. I placed monitor points, from y = 0 to the center of the geometry at a given section, and it seems that code saturne is calculating a velocity at the wall too (at y = 0 I have a velocit...

Thank you very much, Yvan

Hello, I need to access the velocity, on x, y and z direction, from inside the cs_wall_functions_2scales_log, "cs_wall_functions.h" file. I assume the variable "vel" is the velocity in the x direction, it is correct? From doxygen documentation, I understood that I should use this...

Can somebody help me?

Thank you,
