Operator
PROJ_MATR_BASE





1 Goal
To project a matrix assembled on a base of mechanical clean modes or a basis of RITZ.
The projected matrix result will be used by the calculation algorithms in generalized components
(
DYNA_TRAN_MODAL
[U4.53.21] for example).
One can use
MACRO_PROJ_BASE
[U4.63.11] to treat several matrices simultaneously.
Product a concept stamps generalized of type
matr_asse_gene_R
if the matrix assembled with
to project is of type
matr_asse_depl_R
or of type
matr_asse_gene_R
.
Product a concept stamps generalized of type
matr_asse_gene_C
if the matrix assembled with
to project is of type
matr_asse_depl_C
or of type
matr_asse_gene_C
.
