2. User vision of an order

For example, let’s take the AFFE_MATERIAU command, which allows you to assign material characteristics to a mesh. Here is a possible use of this command in the command file provided by the Code_Aster user:

field = AFFE_MATERIAU (MAILLAGE = mail,

AFFE = _F (TOUT = “OUI”, MATER = steel) )

When using a command, it appears:

• the « user » name of the concept produced by the command: cham

• the name of the command: AFFE_MATERIAU

• one or more factor keywords: AFFE

• simple keywords: TOUT, MATER, MAILLAGE

• « user » names of argument concepts: steel, email

• simple values (integer, real, text,…) alone or in a list: “OUI”

From the user point of view, by writing a name to the left of the « = »sign of the command, we assign this name to the result of the command.

This « user name » is assigned a product concept (or data structure) calculated by the operator and whose type is given by the supervisor. The type of product concept is defined in the order catalog (See paragraph Rédaction du catalogue de commande).

For example, field is the user name for the result of the command and to this name is associated the type concept cham_master.
