Operator
PROJ_VECT_BASE


1 Goal
To project a vector assembled on a base of mechanical clean modes or a basis of RITZ.
projected vector could be used by the calculation algorithms in generalized components
(
DYNA_TRAN_MODAL
for example [U4.53.21]).
One can use
MACRO_PROJ_BASE
[U4.63.11] for these projections.
Product a concept of the type
vect_asse_gene
.

3 Operands
3.1 Operand
BASE
BASE = Ba
Concept of the type
mode_meca
or
base_moda
,
mode_stat
or
mode_gene
for
under-structuring which contains the vectors defining the subspace of projection.
3.2 Operand
NUME_DDL_GENE
NUME_DDL_GENE = nu_gene
Classification associated with the generalized model.
3.3 Operands
VECT_ASSE
/
VECT_ASSE_GENE
/VECT_ASSE = goes
Concept of the type
cham_no_DEPL_R
, assembled vector which one wishes to project.
/
VECT_ASSE_GENE = goes
Concept of the type
vect_asse_gene
, assembled vector resulting from the under-structuring, that one
wish to project.
3.4 Operand
TYPE_VECT
TYPE_VECT = typ
Character string describing the type of the field represented by the assembled vector, defect
one awaits a field of the type forces
“FORC”
the other possibilities are
“DEPL”
,
“QUICKLY”
, and
“ACCE”
.
