We are happy to announce a new preCICE release v2.0. https://github.com/precice/precice/releases/tag/v2.0.0

preCICE is a coupling library for partitioned multi-physics simulations, including, but not restricted to fluid-structure interaction and conjugate heat transfer simulations. Partitioned means that preCICE couples existing programs (solvers) capable of simulating a subpart of the complete physics involved in a simulation. This allows for the high flexibility that is needed to keep a decent time-to-solution for complex multi-physics scenarios. Ready-to-use adapters for well-known commercial and open-source solvers, such as OpenFOAM, deal.II, FEniCS, SU2, or CalculiX, are available. preCICE is an open-source software under the LGPL3 license. https://www.precice.org/

We decided to move to v2.0 to clean up some old baggage. Users need to change a few things in their applications to move to v2.x, but it’s worth it, many things will get much simpler. To help moving, we prepared a porting guide: https://github.com/precice/precice/wiki/Porting-adapters-from-preCICE-1.x-to-2.x).

A few highlights:

- The Python bindings are now really pythonic and available through PyPI: https://pypi.org/project/pyprecice/

- We now also have Matlab bindings.

- Configuration of OpenFOAM cases now directly use an OpenFOAM dictionary.

- We did several optimizations to better support very large cases.
