Fluid-Solid Interactions Module
July 2020 – September 2020
Aim:
Accuracy and robustness are essential in multiphysics-coupled simulations. FSI is a challenging example of obtaining an accurate and robust solution. In this context, the aim of the project is to achieve convergence study for 2D FSI simulation using Kratos software as shown in Figure.
It consists in a 2D convergent fluid channel that contains a flexible wall structure attached to its bottom wall. The reference solution has been modeled by mok (2001) and Valdés (2007). It’s a challenging coupling problem due to the similarity between the densities.

The following steps involved:
- Analyse popular FSI benchmarks.
- Mesh refinement studies on the chosen FSI examples.
- Salome environment will be used for the generation of the meshes.
- Time scheme dependency studies on the FSI examples.
