5. Paragraph Operands

For each operand, the meaning of the operand for this command, the nature and type of arguments expected by the keywords, and the restrictions and difficulties of use are described.

For example, in the documentation for operator AFFE_MATERIAU, for operand AFFE, operand intended to specify on which topological entity (s) of the mesh with name ma will be assigned the material with the name mat produced by the operator DEFI_MATERIAU, we will read:

♦ AFFE

Keyword factor that makes it possible to assign different materials to « pieces » of the mesh.

/TOUT = “OUI”,

This keyword allows you to affect all the meshes of the mesh.

/GROUP_MA = lgma,

This keyword allows you to assign mesh groups to a list of mesh groups.

/MAILLE = lma,

This keyword allows you to assign to a list of mesh cells in the mesh.

Each group of elements (keyword GROUP_MA) or each list of cells (keyword MAILLE), or even to the entire mesh (keyword TOUT) is assigned a matt material, which is a concept produced by one of the operators DEFI_MATERIAU [U4.43.01] or DEFI_COMPOSITE [U4.42.03].

If a mesh appears explicitly (or implicitly) in several occurrences of the keyword factor AFFE, the overload rule is applied: the last assignment takes precedence [U2.01.08].
