A few simple examples on using Salome - Code Aster platform

  1. Partitioning
    With Salome it took me quite some time to find out how to define different volumes in one construction that are meshed in one 'piece'.
    In this example four different volumes by partitioning a construction are defined.

      • fuse - partition - compound

  2. Various shell examples

      • from version 11.x: CALC_CHAMP, POST_CHAMP, PROJ_CHAMP

  3. My description of ASTK

  4. Use of Python lists
  5. Use of beam elements

  6. Convergence of solid and shell elements
    This contribution is mainly a comparison between solids and shells (coque_3d) elements on convergence of the displacements.
    Stresses in centre and outside layers
    A small detour on how to determine the stresses at the centre and outside layers of shell elements
    Printing reaction forces and stresses in a table
    The retrieval of the the nodal forces, reaction forces and stresses into a table are discussed (for solid elements only).

    • key words
      • coque_3d, hexahedron and tetrahedron elements
      • convergence rate - shell, hexahedron and tetrahedron, linear and quadratic elements
      • stresses in three different layers: [top - sup], [centre - moy], [bottom - inf]
      • creation and printing of quantities to tables

  7. Applying forces on line segments
    Using a simple spring construction, forces are applied on nodes, a line segment and surface
    Contrib:KeesWouters/spring
    • key words
      • apply loads on nodes, lines and areas: FORCE_NODALE, FORCE_ARETE, FORCE_COQUE
      • define groups of nodes: defi_group, crea_group_no, crea_group_ma
      • orientation of the shell elements ORIE_NORM_COQUE
      • local and equivalent stresses at top, centre and bottom layer

  8. Applying cylinder boundary conditions
    Applied on a simple block with a cylindrical hole the use of LIAISON_DLL is shown to simulate a cylindrical coordinate system

    • key words
      • LIAISON_DDL
      • simulated cylinder coordinates and boundary conditions
