1. Generalities

A nume_ddl_gene is used to define the numbering of the generalized coordinates of a system associated with a modes_meca projection base or based on a modele_gene concept resulting from the substructuring.

The projection of vectors or matrices, assembled according to this nume_ddl_gene on the modes of the projection base or on those of the modele_gene, resulting from the substructuration respectively creates concepts of generalized vectors or matrices (vect_asse_gene resp. matr_asse_gene)

The number of terms or equations of the generalized vectors or matrices depends on the number of modes taken into account in the nume_ddl_gene concept.

The generalized matrices are stored in a single block according to a diagonal storage (in this case, as many terms as modes) or full (in this case, its terms are arranged as a half symmetric matrix in its object “). VALM “).
