Hi,

in version 5.0.4, how can I deactivate the monitoring output for specific user-defined time-averages, which I have defined before in cs_user_parameters.c? I have tried to set keyvis to POST_ON_LOCATION only (without POST_ON_MONITOR), but it didn't work.
Many thanks,
Philipp

I have found the solution in the meanwhile: cs_time_moment_define_by_field_ids("u_avg", n_fields, moment_f_id, moment_c_id, CS_TIME_MOMENT_MEAN, cs_glob_time_step->nt_prev + 1000, /* nt_start */ -1, /* t_start */ CS_TIME_MOMENT_RESTART_AUTO, NULL);

Hi, In Code_Saturne version 4.0.4., I want to write out time averages of a number of variables, for which I aim on using cs_time_moment_define_by_field_ids() in cs_user_parameters.c like this example: int moment_f_id[] = {CS_F_(u)->id}; int moment_c_id[] = {-1}; int n_fields = 1; cs_time_moment_defi...

Hi,
I just wanted to bring this one up again; in the meantime I took a look into cs_wall_functions.c, where the variable iwallf is used. The values for iwallf do not match with the description in doxygen on that specific variable.

Thanks for consideration,
Philipp

Hi, In CS version 4.0.4, I want to force the wall function to be turned off in LES, even for a very coarse mesh (y+ >= 10.88). In clptur.f90, I would therefore just include itytur.eq.4 in line 696 as: ! No wall functions for low Reynolds models if (iturb.eq.0.or.itytur.eq.5.or.iturb.eq.32.or.itytur....

Hi Yvan, Again thank you for the fast reply. I worked around this issue, which originally came up in because I was coupling two code_saturne simulations (hybrid RANS/LES): The subroutine grdvec was called within cscpce, and it was described in grdvec that ivar = 0 would allow to calculate the gradie...

Hi, I am using CS 4.0.4 and I would like to calculate the gradient of a vector field I have created in uspisu and initialized with cs_user_initialization, according to the given examples in the files. I tried field_gradient_vector on my created field in cs_user_extra_operations: call field_gradient_...

Hi Yvan, Many thanks for your fast reply! My CS version is 4.0.4. Both methods work, however, it seems that in LES mode, ivisla and ivista are not created somewhere else in the source code. (I grepped for ivista and only found it for RANS turbulence models.) Thus, I only used the parts call field_se...

Hi,

I would like to retrieve the SGS viscosity from the previous timestep in LES mode. The variable ivista doesn't seem to be calculated in LES, and field_get_val_prev_s is also not working for ivisct. Do you have any hint how to solve my problem?

Many thanks in advance.
