1. But#

Calculate one or more assembled matrices (stiffness, mass, damping…) as well as one or more assembled vectors.

This command is recommended for creating the concepts needed for dynamic calculations, whether they are matrices or vectors. It avoids tedious calls to « basic » commands: CALC_MATR_ELEM [U4.41.01], [], NUME_DDL [U4.61.01], ASSE_MATRICE [U4.61.22], CALC_VECT_ELEM [U4.61.02], ASSE_VECTEUR [U4.61.23].

Produces one or more data structures of type matr_asse_* and cham_no plus, possibly, a data structure of type nume_ddl.
