== Introduction ==
This plugin implements the seismic ground motion simulation method from the smelt project. Note that this plugin generate only non-stationary ground motion. Therefore, you have to make sure your simulation is non-stationary. In python this can be done as follows:

{{Code|code=
# assume your simulation object is 'sim'
sim.Stationarity = False
}}

== Vlachos et al 2018 ==
This feature belongs to the [[RPS_Feature_Group#Simulation_Method| simulation method group]]. This feature implements the seismic ground motion simulation method provided by the [https://github.com/NHERI-SimCenter/smelt Smelt project] which introduced a stochastic model for generating scenario specific ground motion time histories based on the paper: Vlachos C., Papakonstantinou K.G., & Deodatis G. (2018). Predictive model for site specific simulation of ground motions based on earthquake scenarios.

== Dabaghi and Der Kiureghian ==
This feature belongs to the [[RPS_Feature_Group#Simulation_Method| simulation method group]]. This feature implements the seismic ground motion simulation method provided by the [https://github.com/NHERI-SimCenter/smelt Smelt project] which introduced a stochastic model for simulating near-fault ground motions based on the following references: 1. Dabaghi and Der Kiureghian (2014 PEER report) Stochastic Modeling and Simulation of Near-Fault Ground Motions for Performance-Based Earthquake Engineering, 2. Dabaghi and Der Kiureghian (2017 EESD) Stochastic model for simulation of NF GMs, 3. Dabaghi and Der Kiureghian (2018 EESD) Simulation of orthogonal horizontal components of near-fault ground motion for specified EQ source and site characteristics.

* {{PropertyData|ShearVelocity30}}: Soil shear wave velocity averaged over top 30 meters.
* {{PropertyData|DirectivityParameter}}: Directivity parameter s or d --input the larger of the two.
* {{PropertyData|DirectivityAnge}}: Directivity ange parameter theta or phi --input corresponding value to s or d.
* {{PropertyData|SimulationNumber}}: Number of simulated ground motion time histories that should be generated (number of different model parameter realizations).
