Hello Yvan,
Thankyou very much,I have already tested those code.
So I want to change the ...

Hello Yvan,
Now I enconunter a stupid question...
The mesh that I used is explored from Gambit,so the Units are in meters not in millimeter.
How should I set the program to change the units into millimeter? Or which subroutine should I use to solve this question?

Hello Yvan,
Thank you for your sincere reply.I have noticed that most of answers of the questions are your replies,that must be very busy.So I try to learn this soft by reading some cases on this forum.
Now I have added cs_user_extra_operations.f90(already been modified) into SRC and it can run,but ...

Hello Yvan,

I have read some of cases in this forum those days,lots of people use the turbomachinery module to do some simulations.And as you pointed out,I read some cases about cs_user_extra_operations.f90 in this forum,but I don't have any progess.I don't know how to use the subroutine.What I ...

Hello Yvan,
As you said in your reply ,I named those faces with different numbers and I use "1 or 2 or 3 or 4 or 5 or 6"as the selection criteria for the face joining in the "Turbomachinery" section.
Now,it seems to work well.
And the question is that I have selected to post the normal and ...

Hello Yvan,
Thank you very much.
Cause of my shoddy computer didn't work today,I will try it tomorrow.Generally,what I want to solve is to evaluate the forces acting on the blade by using code_saturne.So i want to find a correct settings of the code_saturne.
Thank you again for your reply.

Hello,

If I understand your description correctly, simply use "1 or 2 or 3" as the selection criteria for the face joining in the "Turbomachinery" section (assuming your face groups really are named 1, 2, and 3; adjust for names if needed).

Hi Yvan,
Thank you for your reply ...

Dear admin:
I am a fresh hand of using this software,but the model of turbomachinery attracted me a lot.
Now i want to use this model to simulate a water turbine.This machine is just like a wind turbine.I don't know how to define the boundary conditions of the interface .As is shown in the picture ...
