| Guidelines |
| The thesis should consist of the following steps:
1) Review of paper [1], where an SPH method for both fluids and solids was developed. 2) Review of the SPH method and simple numerical tests using SmoothedParticles.jl framework [2]. 3) Review of fluid-structure interaction (FSI) problems in continuum mechanics, for instance the Turek-Hron benchmark [3]. 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 the behavior of continuous fluids and solids. The method is beneficial 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 (FSI). The goal of this thesis is to approach that questions. If SPH turns out to be useful for fluid-structure interactions, it could greatly simplify and speed up the simulations FSI. |
