Description

Time array containing times at which the specified condition will change its satisfaction status. Determination is performed within the interval list using Sampling and Convergence parameters.

Object Model

Public Properties

Condition	The condition component.
Convergence	The Convergence definition, which uses time tolerance to determine when crossing times are found.
CustomTimeLimits	Specify the interval list within which satisfaction crossing times are sought. The default is set to overall availability of host object. The time limits will be used if UseCustomTimeLimits is set to true.
Sampling	The Sampling definition, which can use a fixed step, relative tolerance or curvature tolerance. Relative tolerance uses a combination of relative and absolute changes in scalar values between samples. Curvature tolerance also uses changes in slope between samples.
SatisfactionCrossing	The direction of interest for satisfaction crossing.
SaveDataOption	Determine if computed satisfaction crossing times are saved/loaded, or recomputed on load if necessary.
UseCustomTimeLimits	Indicate whether to use specified custom time limits (see CustomTimeLimits).

Example
