Modeling e ============== Modeling uses the same calculation in the form of a classical calculation by substructuring. The main structure and the modification are described on a modal basis. The assembly of the two substructures is done classically with the command DEFI_MODELE_GENE. For more details, refer to documentation U2.07.03 (section 4).
