3. Operands

3.1. Operand NUME_DDL_GENE

♦ NUME_DDL_GENE = nu_gene

Name of the nume_ddl_gene concept from the operator NUME_DDL_GENE [U4.65.03] which defines the numbering of the equations of the assembled generalized system, the mode of storing the coefficients of the assembled generalized matrix (sky line) and the generalized model on which the generalized assembly operations are performed, and the generalized model on which the diagonal, or full, assembly operations are performed.

3.2. Operand METHODE

◊ METHODE = “CLASSIQUE”

Construct a generalized numbering allowing the connection equations to be taken into account by the Lagrange or elimination double multipliers method (see R4.06.02). The method used is chosen in accordance with the method specified in the NUME_DDL_GENE operator [U4.65.03]

◊ METHODE = “INITIAL”

Initialize a null matrix of the type Matr_asse_Gene_R that can be filled by Python methods. This method was created for development.

3.3. Operand OPTION

♦ OPTION

The option allows you to determine the list of macroelements, contained in the modele_gene concept from DEFI_MODELE_GENE [U4.65.02], to be assembled. It therefore defines the type of the generalized assembled matrix calculated by the operator ASSE_MATR_GENE.

“RIGI_GENE”: “RIGI_GENE_C”	calculation of the assembled generalized stiffness matrix, including the terms associated with the multipliers of LAGRANGE, calculation of the complex generalized stiffness matrix,
“MASS_GENE”:	calculation of the assembled generalized mass matrix,
“AMOR_GENE”:	calculation of the generalized amortization matrix assembled.
