General Information

What is deal.II ?

From their documentation: deal.II is a C++ program library targeted at the computational solution of partial differential equations using adaptive finite elements. It uses state-of-the-art programming techniques to offer you a modern interface to the complex data structures and algorithms required. A more extensive answer can be found at the deal.II webpage.

What is preCICE ?

preCICE is a coupling library for partitioned multi-physics simulations on massively parallel systems. This includes several features like data mapping methods, parallel peer-to-peer communication, sophisticated coupling algorithms and many more. Comprehensive information are available on the preCICE webpage and the preCICE wiki.

Aim of this adapter

This adapter has two use cases: On the one hand, it provides coupled structural solvers, which could be used for FSI simulations steered by preCICE. On the other hand, it serves as an example of how to couple your own deal.II project with other solvers using preCICE. Have a look in the 'build your own adapter' section for more details.
