Define configurations to be dealt with

Write specifications of the project
Navigation in complex environnments
  • Review of existing hierarchical description methods (adaptativ meshing, structuration adaptée et contextuelle, algorithme adaptatif, regroupement d'objet)
  • Rank different algorithms depending on possibilities of geometric represesentation  and on physic constraints
Homogeneisation process
  • Output choice to analyse the influence of the heterogeneities on the field repartition
  • PRZ definition (Predominance Radiative Zone): zone scattering most (e.g. 80%) of the energy at a given point.
  • Homogeneisation process: assessment of the homogeneized reflexion coefficient  for a given PRZ in order to improve the acuracy of the specular reflexion classical computation
  • Experimental validation
Implementation in a demonstration tool
  • Include methods and algorythms developped in WP 1&2
  • Compare simulations and measurements
