Detailed Description

Check whether value has changed.

Available PostProcessors:: "15": Check whether value of 0d result has changed

check whether a value has changed with respekt to the previous event.

User definable Parameters:

Processor/%name%/{InputName}
The Processor name that contain the 0D result that should be monitored.

Processor/%name%/{Difference}
The maximum allowed difference between the previous and the current value of the 0D result. Default is 0 which results in a value given by std::numeric_limits<float>::epsilon().
