5. Architecture, ergonomics, performances#

5.1. Ergonomic#

Simplified programming

  • Factorization of finite element catalogs

*Improvement of the performance of reading the mesh in the*.med format

Simplification of post-treatments:

  • Naming of internal variables according to mechanical terminology

Deleting:

  • Removed command DEFI_PARTITION

  • Suppression of printing in CASTEM format

  • Removed direct access to keywords NOEUDet MAILLE

5.2. Performances#

Upgraded version for tools:

  • Release MUMPS 5.1

  • Renumber version METIS: from 4.0 (September 1998) to 5.1.0 (March 2013).

  • Version of PETSc (3.7.3)

  • Release MED 3.2.1

Addition of new features related to x solver s MUMPS and PETSc :

  • Introduction of a new value for the keyword SOLVEUR/POSTTRAITEMENTS =” MINI “

  • Introduction of the LowRank method via the new keywords SOLVEUR/LOW_RANK_TAILLE and SOLVEUR/LOW_RANK_SEUIL.

  • Automatic thread activation

  • Parallel analysis phase in MUMPS

  • Second Level Preconditioner LMP.

Parallelism improvement:

  • Authorization of the parallelism of elementary calculations for macro elements

  • Introduction of a hybrid distribution mode for elementary calculations (SOUS_DOMAINE)
