## Description

Contribute to the development and implementation of a CFD solver within the NEPTUNE project, with a primary focus on large-scale simulations featuring free-surface flows and floating objects. The selected researcher will work on numerical formulations and High-Performance Computing (HPC) software developments for the Eulerian free-surface solver. This includes the implicit interface and boundary representations by means of the level set method, the weak imposition of boundary conditions using Shifted Boundary Method (SBM)-based techniques, and the treatment of moving and floating bodies within the fluid domain. The work will include the implementation in the Kratos Multiphysics framework, the verification and validation against representative benchmarks, the performance-oriented developments for large-scale simulations (i.e., parallelisation), as well as the participation in the communication of the potential scientific outcomes. The researcher will also contribute to the integration
of the solver with NEPTUNE's broader CFD and fluid-structure interaction framework, working under the scientific guidance of the project PIs.
