No, This error comes later.

You must still have an error in you mesh.

Did you check the available groups using Code_Saturne's mesh checking options ?

Did you try to setup both domains separately before coupling them, as I suggested ?

Do those steps first.

Yes the fields are well separated as you had explained! I have two SRC.1 and SRC.2. I replaced in my runcase "d" by [d2, d1]

When I checked my mesh, saturn doesn't detected the errors in the mesh!

When you checked your mesh, did you visualize the available groups (with ParaView, using the "extract blocks" filter, or with SMESH, visualizing groups) ?

Or more simply, could you run a full calculation (at least 1 time step) on just one of the 2 meshes with no boundary condition selection error ?

Hello,

I modified my boundary conditions in "usclim.f90", now Saturne doesn't return the error, I get in the "RESU" (ch.med.1.06261512) and (ch.med.2.06261512) but when I red this files by Salome I get (0!!) (velocity =0, prssure = 0 etc.) for the flui but I have a velocity gradient at the turbine et not the fluid ? Do you have an idea??

So I think the configuration of coupling subroutines "ussatc.f90) are wrong!!! that's why it does nothing i dont have anythings!!

Hello,

Yes it works now, thank you very much!!

But I want to run my simulation in STEADY regime, I chose "steady" in "unisi1.f90" but my simulation is done by unstadeay regime!

Do you have an idea please!

I think as the mesh is rotating it is actually unsteady so cannot be simulated with the steady state solver.

Okay, thank you James!

This is specific to Code_Saturne I think?

Perhaps if you are using the frozen rotor method you can use steady state but I'm not aware of this.

Also if the mesh is moving at each time-step I cannot see how you can use steady state regardless of the code you use?

I used a test on another CFD code using the MRF method (Reference moving frame) that I can turn the simulation using steady regime and I thought it was the equivalent to "frozen" in Code_Saturne.

I will do my calculations in unsteady it is not a problem finally.

Thank you to everyone who gave me an idea to achieve this coupling, thank's for all!!

Do you know how we can define the rotation velocity?

in the subroutine I have defined just OMEGA-Y = 2pi, but I did not set the velocity?

Thanks
