Re: streamwise periodicity
Hello, There are some user examples in.the documentation but they may not be sufficient. When.the code starts a new time step, the current value is copied into val_pre and the new value is computed. What I suspect is happening in your case is that when the source term user-defined function is called...

Re: streamwise periodicity
Hello, Yes, you seem to be using the standard temperature resolution. Do not forget that for enthalpy, you also need to multiply by density and CP. If this is missing your sink term might simply be too small ? What are the other factors (boundary and initial conditions) influencing enthalpy here ? B...

Re: Skin friction coefficient calculation
Hello, I am not sure about the skin friction coefficient. The wall stresses contain not only the pressure, but some terms related to turbulence (I am not sure about the details, but you can search for "iforbr" in src/base/predvv.f90 for versions 8.0 or older, src/base/cs_solve_navier_stoke...

Re: streamwise periodicity
Hello, If you exclude the parallel sum, the values you print are those of MPI rank 0. So if none of the cells assigned to rank 0 (depending on the automatic partitioning) are in the selected region, it is normal to have 0. When you add the parallel sums, do you obtain expected values at least for th...

Re: Problems with Qt5
Hello, The error message explains it all. If you follow the recommendations on the Wiki here (https://github.com/code-saturne/code_saturne/wiki/Pre-installation:-Linux-distribution-packages), you do not need to use pip to install PyQt. Only use pip if you understand its behavior well enough : unless...

Re: Scalars and RIJ ssg
Hello, the beta coefficient is defined by a field that is activated automatically with this model, but whose values must be set by the user. It is set by default to -1 so that if it is not defined, you get the error message you observed (rather than having no error message but not computing what you...

Re: streamwise periodicity
Hello, I do not see any obvious error in your code, except that it does not handle parallel summation of values such as total_volume, total_enthalpy, or feedback_term. Unless you sum those using a function such as cs_parall_sum (see examples), your code will be correct only as long as you run on a s...

Re: use a deformed mesh (med file)to restart code saturne calculation
Hello,
It is possible but I would recommend re-buildi g and installing code_saturne with that version also.
Best regards,
Yvan

Re: use a deformed mesh (med file)to restart code saturne calculation
Hello, If I understand correctly your issue is about converting a MED file to an older MED version ? The simplest solution (to avoid this) is to build code_saturne with the same MED version as code_aster, or vice-versa. It might also be possible to modify code_saturne's MED output to write in a comp...
