Hello,

Thank you Yvan for your answer.

I made a little modification to the file 'cs_turbomachinery.c', I deleted the call "if (tbm->n_rotors > 0)" and then imposed the transformation matrix (making it only a translation) using "cs_user_turbomachinery.c".

I got some errors which suggested to me to ...

Hello,

As I started modifying the code, there are things that I didn't really understand, if you can help me with it please.

the function : static inline void
_apply_vector_transfo(double matrix[3][4],
cs_real_t c[3])
{
int i, j;
double c_a[4] = {c[0], c[1], c[2], 1.}; /* homogeneous coords ...

Hello,

Thank you for your answer.

Sorry for the confusion I meant by a new velocity, the velocity of translation of the mesh (domain), can you help me with the way I can impose it ?


I have a second question, for the rotation (already exisitng in the code), can I make the movement periodic in ...

Hello,

Thank you for your answer, what doy mean by globally conservative ? in all domains ?

I can't see how I can impose a new velocity, is it already defined in the code(somwhere else) or I should create a new one ?

If it's the case, can you help me with that ?

Thank you,

Hello Yvan,

Is there any example on how we can translate a mesh ?

Which part of _update_geometry should I modify ? the update of the coordinates ?

In the ALE module, there is the subroutine "cs_user_boundary_conditions_ale.f90" where we can impose a translation to some nodes, is it possible to ...

Hello,

Thank you Yvan for your answer, I had a problem in my installation, so I didn't not find the navstv.90 and the cs_turbomachinery.c where they should have been. But now I fixed it.

Can you help me with what I should modify in the update_mesh function ? it calls a lot of functions and I can't ...

Hello,
Thank you Yvan for your answer.

As a first try, I only imposed a rotation using the cs_turbomachinery.c subroutine. I have some results, but as mentionned in the Turbomachinery module usage in Doxygen, "the code/code coupling approach is not fully conservative", so even the velocity is not ...

Thank you for your answer, I can't see how I can impose a translation using the turbomachinery subroutine, can you help me with that ?

Hello,

I'm working on a case of Fluid-Structure Interaction with Saturne-Saturne coupling using overset method, and I have 2 questions please.

I tried a coupling of 2 meshes without moving one of them, I get a continuous velocity between the 2 meshes, but the stress and the pressure are not ...

Hello,
Here is the mesh I used, and the case I'm working on.

I uploaded it on Wetransfer because I couldn't post it here
