See > **[Release v3.4.0 · precice/precice](https://github.com/precice/precice/releases/tag/v3.4.0)** > > Dear preCICE community, > We are happy to announce a new preCICE release v3.4.0. > This release adds configurable awareness of physical bounds to quasi-Newton acceleration. The consistent partition-of-... actual calculix adapter is with version 2.20.1 quite old. Perhaps a Meeting in Munich by TUM and MTU can solve this. In Doku precice 3.0.x is here a team with calculix 2.20 and the adapter 2.20.1. So perhaps an update is here needed to use all features of new precice 3.4.0. A great project to couple calculix with other codes with FSI, DEM and more physics. Here the Roadmap of precice: > **[Roadmap](https://precice.org/fundamentals-roadmap.html)** > > We are actively developing preCICE. These are some of the features you can expect in the future. ---

Yes. Most tutorials at precice are done with calculix and openfoam to solve FSI and more. Openfoam adapter in active development also with releases each year by org or in 6-month by com. But is now a chance to make a great step to calculix 2.23 or next 2.24. ---
