Hello Yvan, Thank you for your help. You will find enclosed the SRC files for the internal coupling with manual nodes displacement. The code compiles but gives weird results (as if the disale field at time n was not correctly got). The idea is to get the displacement field of the structures defined ...

Hello, I tried to impose the displacement of the nodes in the domain using an custom interpolation of the structure displacement from the cs_user_boundary_conditions_ale.f90 but I get a SIGSEGV signal. Is it then compatible to run an internal coupling calculation by imposing displacement of certain ...

Hello,

Which boundary condition has to be written in the file cs_user_boundary_conditions_ale.f90 for the boundaries which displacement is imposed by the internal fluid-structure coupling ?

Thank you in advance.

Hello,

Thank you for this feedback. In a first approach, I have only imposed a high value of the mesh viscosity closed to the borders without imposing any vertex displacement.

Thank you for your support.

Hello Yvan,

Thank you for your reply. I have added the second picture where the mesh problem occurs.

Hello, I am performing a Fluid-Structure interaction calculation by means of the internal coupling of Code_Saturne. The meshed geometry (constituting the fluid domain) is herein joined (1st picture). Firstly I imposed a displacement on the structure and the simulation worked well with the self-made ...

Hello, Yes I associated the writer as below: cs_probe_set_t *pset = cs_probe_set_create_from_segment( "probes_set" , n_probes , P1 , P2 ); int writer_ids[] = {CS_POST_WRITER_PROBES}; cs_probe_set_associate_writers(pset, 1, writer_ids); cs_probe_set_auto_var(pset, "true"); But no ...

Hello,

I finally created the probes without the creation from segment as proposed within Code_Saturne.

Kind regards,

Hello, I'd want to create a set of probes in order to post-process the main fields (Pressure, velocity, Mesh Velocity) at specific location. When I set a single probe by means of the function "cs_probe_set_add_probe" after creating the probe with "cs_probe_set_create", the main f...

Hello Yvan,

Actually it indeed works by visualizing the results through the WarpByVector filter in Paravis as you mentioned.

Thanks a lot for your support !
