Using solids4foam with preCICE

preCICE is an open-source coupling library for partitioned multi-physics simulations. It can couple a solids4foam solid solver to an OpenFOAM fluid solver, or to any other fluid solver preCICE supports, as an alternative to solids4foam's own fluid-solid interaction solvers.

Both preCICE and the preCICE OpenFOAM adapter must be installed:

• preCICE quickstart
• OpenFOAM adapter

Where the cases live

solids4foam's preCICE cases are maintained upstream, in the precice/tutorials repository, not in the solids4foam repository. Start with perpendicular-flap, whose solid-solids4foam participant is the reference solids4foam configuration, and see the full list of preCICE tutorials.

These cases are run against the solids4foam development branch in solids4foam's own continuous integration, as well as by the preCICE system tests, so they track both projects.

Archived cases

Up to and including v2.4, the solids4foam repository also carried two standalone preCICE cases in tutorials/fluidSolidInteraction-preCICE:

• flexibleOversetCylinder, an overset fluid mesh coupled to a deformable ring, documented on its own page;
• 3dTube, the preCICE version of the 3dTube fluid-solid interaction case.

They were removed after v2.4, as no test covered them. The case files remain available here:

• fluidSolidInteraction-preCICE.zip
