Code_Saturne User's Forum

Hello Yvan, Thank you very much for your support! I tried to initialize uet, but I keep having the same error SIGSEGV signal, as in the first post. Could you give me some more guidance or some examples on how to save variables from cs_wall_functions.h subroutine? I attached the files that I am using...

Hello everyone, I am running k-omega SST, with no wall function, simulations on a straight channel. I need to save to the post-processing results the friction velocities uet(ustar) and uk. From the forum discussions I understand that I need to use the "cs_user_postprocess_var.f90" file in order to s...

Hello Yvan, I could not find the tools for testing the CGNS file format mesh for the windows platform, I am using windows 10. I managed to solve the problem by reinstalling all the software, Code_Saturne and Icem CFD. Now the simulations are working again. Thank you very much for your support. Best ...

Thank you Yvan for the quick reply! I am using ICEM CFD 16.2. I did not updated the version of any software that I am using. I am using the same software versions as in the past, Code_Saturne 5.0.7 and ICEM CFD 16.2, and everything was fine on the same geometry. When I am using a mesh that I made wi...

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...
