Structure of Data
LISTE_RELA



1 General information
The structure of data
LISTE_RELA
is a “volatile” structure of data which is useful in
operators
of intermediate structure enters the data of the user (them
linear relations with dualiser) and their translation in finite elements of Lagrange (in
LIGREL
of
CHARGE
) and in
CARDS
containing the coefficients of the relations.
Approximately, the idea is as follows: one progressively stores the linear relations (one by one) in
one
LISTE_RELA
(routine
AFRELA
) then one “pours”
LISTE_RELA
in
CHARGE
in end of
order (routine
AFLRCH
).

3.1 Notations
nb_rela
a number of relations stored in
LISTE_RELA
nb_coef_1rel
a number of coefficients of a linear relation (“left” part of the equation)
The coefficients can be:
· realities
· or
complexes
nb_coef_tot
numbers total coefficients of the whole of the linear relations stored in
LISTE_RELA
.
nb_coef_tot = nb_coef_1rel (1) +nb_coef_1rel (2) +…
coef_impo
specified value for the linear relation (“right” part of the equation or “second
member ").
The specified value can be:
· real
· complex
· or
function

3.5 Object
“.RLNT”
This object is length
nb_rela.
It contains the numbers of coefficients for each relation.
RLNT (irela)
: coefficents of the relation numbers
irela
= nb_coef_1rel (irela)
.
3.6 Object
“.RLPO”
This object is length
nb_rela.
It pemet “to point” (for a given relation) in the objects”.
RLCO
“,”.
RLNO
“and”.
RLDD
“. These 3
objects have same dimension and one points there in the same way.
RLPO (irela)
: address in
.RLCO
(for example) of the last coefficient of the relation
irela
.
RLCO (RLPO (irela) - RLNT (irela) + 1)
is the 1st term of the relation
irela
.
3.7 Object
“.RLCO”
This object is length
nb_coef_tot
.
It contains the coefficients (
R
or
C
) of the equations.
3.8 Object
“.RLNO”
This object is length
nb_coef_tot
.
It contains the names of the nodes implied in the relations.
3.9 Object
“.RLDD”
This object is length
nb_coef_tot
.
It contains the names of
CMPS
implied in the relations.
3.10 Object
“.RLBE”
This object is length nb_rela.
It contains the second members of the relations.
RLBE (irela)
: second member of the relation
irela
= coef_impo (
irela
).
3.11 Object
“.RLSU”
This object is length
nb_rela.
It contains an indicator (0 or 1) for saying if each linear relation must be taken into account (or not).
Indeed, before “pouring” the linear relations in
CHARGE
, one examines whether certain relations
are not given in several specimens. If it is the case, one eliminates all the doubled blooms while putting
their indicator with 1.
RLSU (irela):
0: to take into account
1: to be unaware of.
