The thesis should consist of the following steps:
1) Review of the SPH method and simple numerical tests using SmoothedParticles.jl framework [2].
2) Review of paper [1], where an SPH method for both fluids and solids was developed.
3) Review of fluid-structure interaction (FSI) problems in continuum mechanics, for instance the Turek-Hron benchmark.
4) An attempt to simulate an FSI problem using SPH.

Preliminary scope of work in English
Smoothed Particle Hydrodynamics (SPH) is a mesh-less numerical method that discretizes fluids and solids by seeing them as a collection of macroscopic quasi-particles. The quasi-particles then interact in such a way that they reconstruct behavior of continuous fluids and solids. The method is especially useful for problems with a free boundary, where other numerical methods based on meshes (finite elements and volumes) become complicated.

Recently, we have developed an SPH method suitable for both solids and fluids. A question remains open, however, whether the method could be useful in simulations of fluid-structure interactions. The goal of this thesis is to approach that questions.
