1. Generalities

The concepts of dynamic results, whether expressed on a physical or generalized basis, have in common the sd_resu_dyna data structure. This structure is complemented by other objects differentiating between data structures for dynamic concepts expressed on a physical basis (sd_dyna_phys) or on a generalized basis (sd_dyna_gene).

This document describes the sd_resu_dyna hat structure as well as the construction of the sd_dyna_phys and sd_dyna_gene data structures that result from it.

The concepts supported by these data structures are:

• on a physical basis: acou_harmo, dyna_harmo, dyna_harmo, dyna_trans, mode_acou, mode_flamb, mode_meca, mode_meca_c.

• on a generalized basis: tran_gene and harm_gene.

• The mode_gene concept represents the only exception of a generalized concept, supported by sd_dyna_phys.
