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 vect_asse_gene type.

3 Operands
3.1 Operand
BASE
BASE = Ba
Concept of the mode_meca type 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 cham_no_DEPL_R type, assembled vector which one wishes to project.
/VECT_ASSE_GENE = goes
Concept of the vect_asse_gene type, 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”, “VITE”, and
“ACCE”.
