I’m working on the coupled method between OpenFOAM and High-Order-Spectral method. I used the open source software HOS-Ocean ( GitHub - LHEEA/HOS-ocean: This project has migrated to GitLab: https://gitlab.com/lheea/HOS-Ocean ). The communication between these two method is velocity and surface elevati…

Hi @yuanz , any simulation code that works on a mesh should be technically compatible with preCICE. I have not worked with spectral methods, but I understand that you could couple a spectral method based code with a finite volume based code. Of course, you will not have the high order of the spectra…

Check this out, it is the coupling between OpenFOAM and HOS: [image] Data (*) on mesh (**) didn't contain any data samples while attempting to map to mesh (***) Using preCICE Trying to couple an in-house potential solver with OpenFOAM. The potential code has been modified …

Hi Ya_Squall, Is this coupling available for public use, possibly with a tutorial folder? Also with a publication to cite? Thanks

Hi, Hydronautica At this moment the code is still under testing and yet open to the public. The publication is also under review. Thanks

@Ya_Squall thanks for directly answering here! I did not remember that you were also using this code. What is the conclusion from the preCICE perspective? I understand that you have already coupled this code, and that this also covers floating objects. Correct? Please do update this topic with you…

Thanks for sharing your work on preCICE. I have a question about coupling OF with HOS, as far as I know the coupling in preCICE is interface coupling. However, I think you use domain coupling (or I think HOS needs to coupled with OF in domain). How dose it work?

I guess that “domain coupling” means what we call “volume coupling”. This is generally possible with the OpenFOAM adapter, no clue whether this works with HOS: [image] Configure the OpenFOAM adapter Write a system/preciceDict, set compatible boundary conditions, and activate the adapter…

Hi @Ya_Squall My question is: Have you successfully achieved the bidirectional coupling between HOS and openfoam? So far, what has been the progress of your research? Are there any papers available for me to refer to? Thanks

Is it possible to couple OpenFOAM with High-Order-Spectral method base on preCICE?

Is preCICE for me?
