Active Contour: Appears for SIFS and J-Integral (JINT) probes only. Specify the contour for which you want to extract the time history. The default is the maximum solution contour of the crack. Location Method: Read-only property set to Crack Length Percentage. Crack Length Percentage: The default value is `0`. Use this percentage entry to select a node along the crack front tip you wish to examine. By changing the Crack Length Percentage, you should receive time history plot of the crack front node located along the crack front. Suppressed: Suppress or unsuppress the object. The default is No.
Options	Display Time: The default setting is End Time. Specify a time at which you want to extract the results.
Results	Provides read-only extracted values of the probe you select: Result (Display Name depends on probe type) Minimum Value Over Time Maximum Value Over Time
