4. Data structure content EVOL_NOLI#

Data structure EVOL_NOLI contains the list of fields archived during the calculation (according to the various ARCHIVAGE keyword options). By default, it contains, for each moment, the list of fields described in the documentation for STAT_NON_LINE (U4.51.03). In dynamics, it also contains:

  • VITE: speed field (at knots);

  • ACCE: accelerations field (at the nodes);

  • DEPL_ABSOLU: field (at the nodes) of the absolute displacements of the structure (see § 3.4.3);

  • VITE_ABSOLU: field (at knots) of the absolute speeds of the structure (see § 3.4.3);

  • ACCE_ABSOLU: field (at the nodes) of the absolute accelerations of the structure (see § 3.4.3);

When looking for vibration modes, the corresponding field of movement and the value of the frequency are stored.

Note: when calculating REAC_NODA in post-processing (see [U4.81.04]), the absence of archiving field ACCE will give incorrect results.
