Optimization and Optimal Control

OptimalControl

<OptimalControl .../>
Attribute Comment Value
what= Select a time-dependent setting to optimize Select from: SettingInZone

OptimalControlSecond

<OptimalControlSecond what="Velocity-inlet" lower="0.0" upper="0.05"/>

Parametrises a time-dependend Setting with the value of every second iteration. Values inbetween are interpolated.

lower= Lower limit on the value of the Setting Value with unit (float)
upper= Upper limit on the value of the Setting Value with unit (float)

Fourier
