3. Operands#

3.1. Operand UNITE_IDEAS#

◊ UNITE_IDEAS

Logical unit number of the so-called « universal » file IDEAS. The value by default is 19. Care must be taken when declaring the IDEAS mesh file in astk: you declare this file as an input file with the corresponding logical unit (19, if using the default value).

3.2. Operand UNITE_MAILLAGE#

◊ UNITE_MAILLAGE =

Logical unit number for the*Aster* mesh file. The value by default is 20.

3.3. Operand CREA_GROUP_COUL#

◊ CREA_GROUP_COUL =/'OUI',

/”NON”, [DEFAUT]

The user can request the creation of mesh and node groups grouping all the stitches and knots of the same color by specifying CREA_GROUP_COUL = “OUI” in the PRE_IDEAS command. These groups are named COUL_n where n is the color number in IDEAS.

In order not to unnecessarily increase the number of mesh groups and nodes and therefore the size of the mesh file, it is decided not to automatically create mesh groups of the same color: CREA_GROUP_COUL = “NON” [DEFAUT].

Notes:

  1. The command PRE_IDEASne only treats Cartesian coordinate systems.

  2. The command PRE_IDEASne only handles one Cartesian coordinate system.

  3. When converting the universal file IDEAS, the command PRE_IDEASvérifie if the user has defined multiple coordinate systems. If this is the case, an alarm message alerts the user, asking him to verify that all coordinate systems are the same.
