Themes and objectives

ANEMONE aims improving high order (second or more) embedded and immersed boundary methods to describe moving interfaces as well as moving boundary conditions on unstructured grids. The main focus of this associated team are techniques based on ideas similar to the shifted boundary method, developed within the HAMSTER associated team. ANEMONE plans in generalizing these methods and in particular focus on

  • Increasing the order of accuracy embedded methods beyond the second order of the shifted boundary methods
  • Investigate the energy preservation capabilities of the method when applied to wave propagation
  • Handle moving rigid bodies both in inviscid compressible flows, and viscous flows.
  • Use the SBM concept to track moving interfaces between materials with different properties, including coupling incompressible and compressible flow domains
  • Improve the initial work done on shock embedding by applying some pf the SBM ideas to shock traking/fitting
  • Bridging immersed and embedded boundaries, and more particularly construct high order penalization techniques based on ideas similar to those of Brinkman’s method
  • Investigate the role of mesh adaptation in high order embedded/immersed methods
  • Introduce some multi-scale/multi-physics flavour in the embedding by coupling with other PDE based as well as Reduced Order models to account for sub-mesh effects, or for the variations  of some set of parameters affecting the boundary conditions embedded
