== Introduction ==
This feature allows the user to simulates random wind velocity according to the conventional spectral representation method proposed by Masanoby Shinozuka and George Deodatis (1991).

[[Image:Plugin_WindLab_ShinozukaAndDeodatis1991_Screenshot_1.png|1024px]]

== Shinozuka and Deodatis 1991 ==
This is the only RPS feature that the plugin implements. It belongs to the [[RPS_Feature_Group#Simulation_Method| simulation method group]].

=== Feature Dependency ===
The features required by this feature are summarized in the following table:

* A [[RPS_Feature_Group#Location_Distribution| simulation points feature]]
* A [[RPS_Feature_Group#Frequency_Distribution| frequency discretization feature]]
* A [[WindLab_Feature#Mean_Wind_Speed_Profile| mean wind speed profile feature]]
* A [[RPS_Feature_Group#Randomness| randomness provider feature]]
* An [[WindLab_Feature#Along_Wind_Spectrum| along wind spectrum feature]] or an [[WindLab_Feature#Across_Wind_Spectrum| across wind spectrum feature]] or a [[WindLab_Feature#Vertical_Wind_Spectrum| vertical wind spectrum feature]] depending on your wind velocity component.
