**Version 3.4** of |app| was released **September 29**. The following lists the functionality available in this current version. (Note: New features and fixes in this release are marked :blue:`blue` in the following list of features.)


Structural Information Model
============================

Applications used to specify/select the structural model to be used in analysis.

#. MDOF: creating idealized multi-degree-of-freedom models
#. OpenSees: user-defined OpenSees models
#. Steel Building Model: automating steel frame design and modeling
#. Concrete Building Model: automating concrete moment frame design and modeling
#. MDOF-LU: MDOF shear building model
#. SurrogateGP: surrogate model trained in EE-UQ
#. Multiple models: selecting multiple structural information models :blue:`[<- renaming from Multimodel]`

    
Earthquake Motion Event
=======================

Applications used to specify/select ground motions for the structure.

#.  Stochastic Ground Motion: simulating stochastic ground motion recordings
#.  PEER NGA Records: selecting and scaling PEER NGA West2 ground motions 
#.  Site Response: propagating rock motions to the surface
#.  Multiple PEER: using multiple PEER recordings
#.  Multiple SimCenter: using multiple SimCenter-format recordings
#.  User-specified Database: selecting and scaling ground motions from the user-specified flatfile
#.  Physics-based ground motion simulations generate by the `M9 project <https://sites.uw.edu/pnet/m9-simulations/>`_.


Engineering Demand Parameter Generator
======================================

Applications to identify the output parameters of interest given the ground motion and structural model.

#. Standard Earthquake: maximum story drift ratio, lateral story displacement, peak floor acceleration
#. User Defined: user-specified EDP
#. None: used only for surrogate model-based predictions
    
    
Finite Element Application
==========================

Applications used to determine the response output parameters given the ground motion and structural model.

#.  OpenSees: Open System for Earthquake Engineering Simulation
#.  CustomPy-Simulation: user-provided python script`
#.  None: used only for surrogate model-based predictions
#.  Multiple models: selecting multiple finite element applications :blue:`[<- renaming from Multimodel]`
