preCICE

The coupling library for multi-physics simulations

preCICE is an open-source coupling library and ecosystem for general partitioned multi-physics and multi-scale simulations, including surface and volume coupling. 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 coupled problems. The software offers convenient methods for transient equation coupling, communication, time interpolation, and data mapping.

"Which preCICE repositories merge
newcomers' pull requests, and which beginner
issues are still free?"

Those commands read live data: which repositories merge outside pull requests, and which beginner issues nobody has claimed. Install in two minutes.
