I read that you do surface coupling? Do you support volume coupling too?

With release of preCICE version 3.0.0 up to the latest release of preCICE version 3.2.0 there have been many changes and improvements regarding large meshes. The following has a positive effect on volume coupling: Mesh processing, memory footprint, and communication has been substantially improve…

Yes, but it will be computationally expensive. preCICE is mainly designed to couple simulations that share a common surface boundary. In this case, all the coupled volume nodes should be specified in the coupling mesh. preCICE only knows about points and their connectivity, so it doesn’t make much …

For the OpenFOAM adapter, there is an open Pull Request for supporting volume coupling: https://github.com/precice/openfoam-adapter/pull/97 Feedback or further work on this would be very welcome.

We have volume coupling on the radar and are currently gathering plans, ideas, information and work packages in the GitHub issue 468 . Feel free to participate in shaping this feature!

There have also been talks about volume coupling at the preCICE Workshop 2020: 6-way coupling of DEM+CFD+FEM with preCICE Volume Coupling using preCICE for an AeroAcoustic simulation

We have news! We are actively working on a new linear cell interpolation mapping. For 2D cases, you will be able to define a triangular mesh and configure preCICE to interpolate inside the cells For 3D cases, we plan to add support for tetrahedral elements to both the API and the above mapping.

More updates on volume coupling: We recently finished developing a partition-of-unity RBF data mapping. This should be a game changer for volume coupling. Add partition of unity RBF data mapping precice:develop ← davidscn:pou-m…
