Operator DEFI_CONSTANTE
1 Goal
To define the value of an invariant size.
This operator is a facility offered each time a concept of the function type is awaited and that
the data to be introduced is constant. That makes it possible to define, for example, of materials of
characteristics independent of the temperature for commands which make it possible to treat
variable materials of characteristics with the temperature.
Attention not to be confused with the definition of a real parameter (ex: has = 3.).

3 Operands
3.1 Operand
NOM_RESU
NOM_RESU = NR
Indicate the name of the result, the function thus created is a function whose value is of name
NR (8 characters).
In fact, this operand is not useful systematically for checks of coherence, in
execution of the code. These checks of coherence are made by the command
CALC_FONCTION.
3.2 Operand
VALE
VALE = v
Value of the constant (a real number).
3.3 Operand
TITER
TITER = Ti
Titrate attached to the concept produced by this operator [U4.03.01].
4 Examples
·
To define the constant function “1.” :
F_UN = DEFI_CONSTANTE (
VALE = 1. )
Function F_UN represents “any kind of result” (TOUTRESU) by DEFAUT
·
To define a constant function representing a constant YOUNG modulus
F_YOUNG =
DEFI_CONSTANTE
(
VALE = 2.1E11,
NOM_RESU
=
“E”
)
