preCICE stands for Precise Code Interaction Coupling Environment. Its main component is a library that can be used by simulation programs to be coupled together in a partitioned way, enabling multi-physics simulations, such as fluid-structure interaction.
If you are new to preCICE, please have a look at our documentation and at precice.org. You may also prefer to get and install a binary package for the latest release (master branch).
