Main improvements in Code_Saturne version 1.3

Basic Kernel improvements

  • parallel coupling with SYRTHES, including 2D calculations
  • automatic evaluation of total pressure
  • unified outlet boundary conditions
  • unified launch script, compliant with every architecture tested so far
  • single listing file (default)
  • ALE method (mobile meshes) and internal fluid/structure coupling with mobile solid structures (simple spring law)
  • orthotropic mesh viscosity and compatibility of ALE method with second order in time and velocity/pressure sub-iterations
  • steady-state algorithm
  • optimisation for massively parallel machines
  • fine CPU time memory consumption analysis, traceback in case of crash (BFT library)
  • plugging of BLAS libraries when available, for optimised linear algebra
  • rough wall boundary conditions
  • stabilised v2f turbulence model
  • improved algorithm for distance to the wall evaluation (faster and more stable)
  • simplified selection of faces or cells sub-sets (for boundary conditions, initialisation, source terms, post-processing, ...) with criteria on colour, group and geometry, using specific functions (GETCEL, GETFBR, GETFAC)
  • extension of the potentialities of the Graphical User Interface (advanced calculation parameters, advanced selection and post-processing, ALE, steady-state, coal combustion, radiative transfer)


Improvements in Specific Physics

  • Matisse engineering module for the design of nuclear waste storage facilities
  • heavy fuel oil combustion (not fully validated)
  • restructured coal combustion module, accounting for coal humidity
  • wall chemical forces (van der Waals) and advanced fluid/particule interaction in the Lagrangian module
  • compliance of Lagrangian module with periodic boundaries
  • advanced and simplified statistics in the Lagrangian module


Improvements in pre/post-processing

  • direct and parallel post-processinfg through the FVM library, with optional discard or tesselation of non-standard polyhedra or polygons
  • direct and parallel treatment in the Kernel of ghost cells creation (for parallelism and periodicity) and mesh quality measurements, inducing a 50% decrease in memory consumption for the Preprocessor
  • benchmark mode to test the code efficiency on linear algebra operations and parallel communications
  • possibility to define sub-meshes, variable in time, for post-processing purposes, and to write any user-defined variable on them
  • automatic post-processing of boundary forces and Courant and Fourier numbers
  • automatic post-processing of the SYRTHES coupling mesh


Improvements in documentation

  • fully documented tutorial, guiding the user on the setting up and running of five basic test cases
