Re: Scalars and RIJ ssg
Hello,
I have suggested to some colleagues more expert in.the turbulence modeling of the code to check this post... I'll ping them again.
Best regards,
Yvan

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...
