The coupling library for partitioned multi-physics simulations.
preCICE is the leading open-source 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.
The software offers convenient methods for transient equation coupling, communication, and data mapping.

How does it look like?
In this tutorial case,
we couple OpenFOAM with CalculiX for FSI. OpenFOAM starts and waits for CalculiX. After they both start,
they find each other and start performing a serial-implicit coupling with interface quasi-Newton acceleration.
These options are set in the preCICE configuration file
