I want to simulate rotatory machinery, with motion driven by the fluid. Let’s say that I know how to do it in OpenFOAM using the 6dof motion solver. But what if I want to have the deformations of the body using FSI.
Basically I’m asking about how to do it, and maybe it’s a good idea to publish as an example, on the Github site.
what I want is something like this video: https://www.youtube.com/watch?v=G8omE5y5EYI
which was created with EMPIRE instead of preCICE
Thanks!
This is definitely doable by preCICE. Two examples:
In your case, I guess that overset meshes in OpenFOAM could help you with modelling the rotating part, while CalculiX (or more solvers) should be able to model the rotating structure.
I would be happy to help you with the preCICE part and we would be happy to host the example in our wiki at the end. It will definitely be useful for more people. Let’s keep the discussion in this thread, so that everybody experienced in the various aspects can contribute.
Hi Makish,
May I ask if there is any new progress on this topic? I am struggling with how to couple sixDOFRigidbodymotion solver with calculiX. I try to modify the solver step by step followed by your thesis and coupling documents provided on preCICE website. However, I cannot make it. It seems the sixDOFRigidbodymotion isjust a big library, no main function, and fluid solver call it when it needs. After adding preCICE interface heading file, I have no idea how to do next.
Could you give me some tips that how to deal with this problem?
Thanks.
Dear @YujiaWei2020,
the second thesis I was talking about is by Qunsheng Huang: mediaTUM - Media and Publication Server
Other than that, please open a new topic describing your current case and problems and I will be happy to help, to the extent I can. 
Hello, did you manage to make the 6 DOF motion in OpenFOAM work with precice ?
