Linear and non-linear dynamics
==================================


Operator DYNA_VIBRA
--------------------

 The redesign of the DYNA_VIBRA operator has resulted in the following changes:


* Reprogramming of the integration diagram DEVOGEet generalization to all calculations.


* Availability of the integration diagram ITMIpour any transitory calculation and not only IFS.


* Introduction of a new method for the treatment of shocks based on the particularities of IFS, with the keyword TRAITEMENT_NONL = 'EXPLICITE'/'IMPLICITE'.


* Evolution of archiving to allow the user to force the calculation and archiving of moments of interest.


* Treatment of localized non-linear forces (options TRAN/GENE).


* Introduction of unidirectional friction for law DIS_CHOC via the keyword UNIDIRECTIONNEL =/' OUI '/' NON '.


Coupling MISS3D
---------------


* Improved CALC_MISS/DEFI_SOL_MISSavec the further automation of data generation MISS3D


* Improvements to DEFI_SOL_EQUIdont: the introduction of a ONDE_PLANE load of several types with or without conditions at the periodicity limits


* Modification of CALC_MISS/IMPEDANCE_TEMPORELLE for binary file output


Tools
------

**Dynamic analysis on a modal basis:**


* Verification of the physical direction of the damping calculated by the macro command CALC_AMOR_MODAL

 **Signal post-processing:**


* Calculation of coherence functions from time signals via CALC_FONCTION/COHERENCE


* Accelerogram interpolation via CALC_FONCTION/INTERPOL_FFT


* Introduction of macro command CALC_SPECTRE_IPM for modeling floor-hardware interaction


* Introduction of macro command LISS_SPECTRE to automate spectrum smoothing.
