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 s...

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 */ doubl...

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 time or...

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 possibl...

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 s...

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...

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 really c...

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
