Number the degrees of freedom of the overall structure based on the numbering of the substructures.

In the context of a calculation using dynamic substructuring methods (modal or harmonic analysis), the operator NUME_DDL_GENE defines the bijection between, on the one hand, the numbers of the generalized degrees of freedom of each substructure and the numbers of the degrees of freedom of link for each link and, on the other hand, the numbers of the final degrees of freedom (i.e. the row or column indices of the generalized matrices). The numbering being carried out, the operator builds, according to the « sky line » storage mode, the addressing tables necessary for the effective storage of the terms of the generalized matrices assembled with this numbering. Full or diagonal sky line storage is possible to calculate a full added matrix or to solve a transitory problem on a modal basis resulting from a mode_meca concept.
