Hello Yvan,
Thank you. I have found that in turbo-machinery module, but I got another error when running the case:
"SIGSEGV signal (forbidden memory area access) intercepted! " before calculation. Do you know how can I solve this problem? Thank you.
All the best, Yan.

Re: modify the free stream inlet
Hello Yvan, I have install the version 5.2 and found the part called ''internal coupling with a simplified structure model".But I'm not sure how to do that. I have a rotating zone(rotor) and stable zone(stator). how can I achieve that using this coupling model? And what does the velocity and po...

Re: modify the free stream inlet
Hello Yvan, I used the code/code coupling method. The Results are placed in a RESU COUPLING directory, with a sub-directory for ROTOR and STATOR, itself containing one sub-directory per coupled domain. But I can't use the command "RunSaturne_Coupled" ( command not found)..... In addition, ...

modify the free stream inlet
Hello everyone, I used the turbo-machinery module for wind turbine. However, there is always something wrong with face join between rotor and stator. :cry: :cry: :cry: So I'm thinking about that if I can make the turbine stable and change the wind velocity direction(rotating). My question is that in...

Re: lift force calculation
Hello Paul, Yes, you're right. The value is force from the subroutine. I got the same problem with you. The value of drag is much higher than experiments. I used LES(wale). All the best, Yan. Hi Yan, Thanks for the tutorial on paraview. Yet, I think it takes a lot of time, in comparison with the sub...

Re: lift force calculation
Hello Paul, But I have one more stupid question about your attached subroutine. It can get the value the lift and drag coefficient of "Foil", not the force? Thank you very much. All the best, Yan. Hello Yany and Yvan, I'm also working on lift and drag calculations over a NACA profile. I at...

Re: lift force calculation
Hello Paul, Thanks soooooo much for your reply! I really appreciate that. You can try to use Paraview to calculate the drag force. I attached a link from youtube which may tell you how to do that. https://www.youtube.com/watch?v=J944HOj_4b0 All the best, Yany. Hello Yany and Yvan, I'm also working o...

Re: lift force calculation
Hello Yvan, Thank you for the reply. I think that's the point.I used the subroutine for version in version 5.0. Is there any subroutines for version 5.0 could be used to calculate the lift and drag force? I attached the mesh. The direction of free stream velocity is (1,0,0), so that that the directi...

lift force calculation
Hello, I have used code_saturne over 1 year. But by now there is no meaningful result I have got. I just ran a very simple aerofoil case. I used version 5.0.3. The cs_user_extral_operation.f90 which is for lift and drag coefficient cannot link and compile. I don't know why. I attached the file and c...
