This repository contains a collection of validation and use cases showcasing different features of the Kratos Multiphysics Finite Element Framework.

Each folder presents cases on a given area, organized as follows:

• Use cases: Complete cases showcasing a given feature or application.

• Validation: Benchmark problems (academic or otherwise) that can be compared to reference data from scientific literature.

Each case should be self-contained: include all input data and relevant scripts so that users can test it. It should also be accompanied by a page (a simple file such as this readme, or a full wiki page) presenting it and linking to reference results, if available in the literature.

Unit tests should not be uploaded to this repository. Please put them in the tests folder of the corresponding application.
