DESCRIPTION:Frédéric Schwander\nPower exhaust\, particle and energy spat
 ial distribution are key to the performance of tokamaks. Understanding the
  relation between these aspects and plasma properties\, plasma scenario an
 d plasma-facing components is instrumental in the design of optimized plas
 mas on the way to energy production through fusion.\n\nThe laboratory M2P2
  (Aix-Marseille Université\, CNRS\, Ecole Centrale Méditerranée)\, alon
 g with several collaborating research entities\, is involved in the develo
 pment of numerical tools towards the modelling of particle and energy circ
 ulation in the tokamak as well as heat flux on plasma-facing components th
 rough the 2D fluid transport code SolEdge-HDG. The latter is a steady-stat
 e solver\, based on a high-order finite-element spatial discretization nam
 ed Hybridizable Discontinuous Galerkin\, in which the geometry of the wall
  is fully taken into account by adequate meshes that are constructed regar
 dless of the magnetic field.\n\nThe presentation will first bring a short 
 introduction to Discontinuous Galerkin methods for the non-specialists\, b
 efore moving to Hybridizable Discontinuous Galerkin methods\, their workin
 g principle\, distinctive features and perceived advantages. The presentat
 ion will then focus more in-depth on the code Soledge-HDG through a brief 
 overview of the underlying physics\, of the equations solved\, general alg
 orithm and workflow for a typical simulation. A final part will describe r
 ecent works\, highlighting the capacity of the code to deal with time-vary
 ing magnetic fields and adaptive mesh refinement.
