Installation_configuration_errors
Hi, Hope you are well. I am using Code_Saturnev5.0.8 in Ubuntu 16.04 on a desktop machine and works fine. Now, I tried to install the same version in Ubuntu 18.04 in a laptop machine though I run into some errors while configuring the code , any ideas? Please find attached the config log. I used Sal...

Re: Wall_shear_stress_from_post_util
Dear Yvan, Thank you for your reply. I thought of finding a way to call directly the friction velocities from clptur.f90 i.e rho uk*uk and compute the wall shear stress. I supposed this is from where the code compute the efforts. Though, is it possible to make a call for the variable uk in that rout...

Re: Wall_shear_stress_from_post_util
Dear Luciano,
Thanks for you reply. I will check it though I do not know how valid is that approach if you use standard k-epsilon.
Regards,
Costas

Wall_shear_stress_from_post_util
Hi, Hope you are well. I would like to ask you how can I perform a time average of the wall shear stress on the vertical wall of a square cavity i.e from the tutorial examples. I know the tangential stress can be called from post_util.f90 and pass the information in the cs_user_extra_operations.f90 ...

Re: Low value of Turbulent heat fluxes in Natural convection
Hi,
Thanks for the clarification. Another question if you do not mind. If you use Boussinesq through cs_user_source_terms.f90 under ustsnv what did you do with the gravity vector in the generation rate of turbulence (Gk)?
Cheers,
Costas

Re: Umist_wall_function
Dear Jean-Francois Wald, Thank you for your reply. Another question that I have is what is the value imposed regarding the dissipation rate of the near wall node? As far as I understood, a neumann boundary condition is imposed for the dissipation rate of the flux concerning the face node, . Best reg...

Re: Low value of Turbulent heat fluxes in Natural convection
Hi,
May I asked how did you implement Boussinessq?
i.e cs_user_source_terms.f90 under ustsnv or cs_user_physical_properties.f90 under usphyv?
Cheers,
Costas

Re: Umist_wall_function
Hi, I have read the clptur.f90 but I need some explanations. Firstly, I was looking at the formulation of the standard wall from the literature function Pk_on_cell.png and the one implemented in Code Saturne. My question is where are the Pk and average epsilon terms go in the code if the are the sam...

Re: Umist_wall_function
That would be great!thanks.
Meanwhile something that will help me is if you can explain what does rcprod in the velocity boundary conditions and pimp in the k-epsilon boundary in the clptur.f90.

Re: Umist_wall_function
Dear Yvan,
I have figured out that what is needed is to modify the boundaries in clptur.90, cs_wall_functions.c/h. Though I was wondering if need to modify also the subroutines of the model turbke.f90 like the production terms. Any ideas?
Thanks
