Hello,

I am currently working on LES of an unsteady case with harmonic forcing. I am collecting time-averaged statistics for various quantities. Is there a way to collect phase-averaged statistics using cs_time_moment_define_by_func ?

I could not easily sketch a way, thus I am currently planning ...

Thank you for the quick reply Yvan !

Hello,

Do you know if there are plans to update the FSI tutorials ?

Cheers,

Hello,

I am running a case with internal coupling and natural convection (Boussinesq). On the solid side, the pressure seems exactly constant and the velocity is zero, as expected. However, when looking at Yplus on coupled faces or when looking at the average / variance of the field "boundary ...

Hello,

Here is the modification in tridim so that I can use ustar in the scalar boundary conditions when doing a restart on a frozen velocity field : I simply call condli twice at the first time step of the restart.

iterns = 1
do while (iterns.le.nterup)

! Calls user BCs and computes BC ...

Thanks Yvan,

During initialization and at the first time step, the friction velocity is exactly zero when used in scalar boundary conditions. But at the second time step, it is updated and no longer zero! I will try to figure out how to force earlier update of the field.

Hello,

It looks like the field "ustar" is zero when trying to use it when imposing scalar boundary conditions after a restart on a frozen velocity field. Any idea to force the code to estimate it ?

Thanks,

Hello,

It looks like the parameter ibeta is automatically defined in base/varpos.f90 when idilat=0 or irovar=1.

When idilat=0, the user should provide the thermal expansion coefficient in a user subroutine, such as usphyv (cs_user_physical_properties.f90). Check cs_user_parameters-base.c if you ...
