7. Modeling E#
7.1. Characteristics of modeling#
The characteristics of modeling E are exactly the same as those of modeling A. On the other hand, the CREA_ELEM_SSD and ASSE_ELEM_SSD commands are used to create and assemble dynamic macroelements. We also present how to create the initial conditions for a transitory calculation on a modal basis by dynamic substructuring. The calculation of the direct response (without substructuring) is not included in this modeling.
