Hello, I'd like to know how the face force is calculated in code_saturne (which can be obtained using field_get_val_v(iforbr, forbr)). I'm using the version 5.0.4, so where are the related subroutines located? And in my simulation, the face force is always 0 at the end of the first iteration, afterw...

Hello, For example, with the file salome/fsi_coupling/libmilieu/runmilieu.c, I have the compilation error like "runmilieu.c:(.text+0x16) : référence indéfinie vers « inicom »" when trying to compile it. If I understand well, the files located in salome/fsi_coupling/libmilieu are compiled a...

Hello, I would like to modify some source files located in code_sature-5.0.4/salome/fsi_coupling in order to perform fluid-structure interaction using Yacs. I know that for source files of code_saturne, we can place it in the SRC directory of a test case, then use "code_saturne compile" to...

Hello,

Yes, I updated the config file. I think they are some configuration issues with salome_meca 2017.

Thanks a lot, I am waiting for your results.

Best regards,

Hello, As you recommended, I began to build my test case using salome_meca2017. However I encountered several problems: firstly, when I launch the application runcase, I have following errors: /home/lzhang/Study_Code_Saturne/Cas/test2017_cylindres_concentriques/RESU_COUPLING/20171211-1525/appli/runS...

Hello, I am using salome_meca2015_2 and code_saturne 5.0.4. Indeed I used Gui to build my test case, and I have no idea where the variable asddlf is rewritten. I would like also to check the face force, as it seems to be very small. Do you you know where the associated file is located? And what do y...

Hello, Thanks for your response! If I understand well, choosing F_z in fix force component has the same effect of setting asddlf(3, 1) = 0, where 3 means the Z direction and 1 means the first defined external structure? So the value of asddlf should be either 1 or 1? Because in my simulation result,...

Hello, I checked the output information and I found that the face force sent by code_saturne is 0. This is very strange, as obviously I have fluid flow in the domain. Maybe there are some configuration errors in my code_saturne set up. Could you please explain the meaning of fix force components in ...

Hello, Yes, my program can run until the end, however the results are probably wrong. I am trying to simulate the impact of fluid over a beam, and I did firstly the code chaining : I ran a code_saturne simulation with only the fluid and save the fluid force to a MED file, then I ran a code_aster sim...

Hello, As you recommended, I'll try with the latest version of salome-meca. I found that the problem at the 10th step was due to the fact that in yacs scheme, the iteration number was defined to be 10. I think that it's a default value given by launching the code coupling. It looks like the program ...
