Hello,
I wanted some help to implement the Umist wall function for the k-epsilon model for buoyant flows. What are the related subroutines needed and if there are any related to the examples, please let me know.
Thanks,
Costas

Time-averaging/residuals
Hi, Few questions concerning the time average and the normalised residuals shown by trackcvg in Code_Saturne v.5.0.8 when unsteady algorithm is switched on. First, how does the time-moments are computed in cs_user_parameters-time_moments.c and how can I know what is the moment_c_id[] value? Secondly...

Re: Turbulent_heat_flux[Y]
Dear Yvan,
Many thanks, I have sorted it out. The parallel operation is call parall_bcast_r(irangv,uu) for r11 array which I assigned to double precision uu.

Costas

Re: Turbulent_heat_flux[Y]
Right, thanks so it will be something like call field_get_val_s_by_name() and what is the parallel assignment?

Turbulent_heat_flux[Y]
Hi, I have a question regarding printing the turbulent_heat_flux[Y] of the EBRSM model. Is there a way that I can call this variable and print it in a file using cs_user_extra_operations_1D_profile.f90? I noticed that it is already printed in the monitoring points and I want it printed along a line ...

Re: Code_Saturne_Automatic scheme and Low_Re_models Convergece
Hi, Thank you all for your replies. I actually used SIMPLEC for the pressure-velocity coupling. I found out that the Rij-espilon EBRSM requires GGDH hypothesis for the scalar temperature. For the rest of the models apparently there was an issue with my mesh which I sorted by splitting the geometry i...

Code_Saturne_Automatic scheme and Low_Re_models Convergece
Hi, Another 2 questions. 1) What is the scheme for the solver in equation parameters? (first choice before centred,upwind etc. in the GUI) 2) I am trying to run a heated channel flow case with low Reynolds number models (v2_BL_v2/k, Rij-epsilon EBRSM) and they do not converge. I run the case with hi...

Re: Temperature_boundary_wall
Dear Yvan,
Thanks for your reply. Basically I am extracting data using cs_user_extra_operations.f90 and I want to extract the boundary wall temperature. I would like to know what is the function that I have to call in order to get the wall temperature (boundary) of my domain?
Best regards,

Temperature_boundary_wall
Hello,
I wanted to ask if there is a way to print the temperature of the wall boundary i.e. between two parallel plates in a file.
Thanks,
