Calculate changes in object property using Back Tracking

Tracking simulation is forward and the property such as density for the stream to extract from the tank is calculated from the property of the tank. But sometimes it needs to set the fixed property for the extracted stream and the property in the tank is re-calculated by it.

For example, the water is drained from the crude tank and there is no water composition in the crude tank but the density in the crude tank shall be changed by this water drain. Normal tracking simulation cannot calculate it. However AVEVA Production Accounting Back Tracking functionality can calculate the change of the density in the crude tank by the backward tracking.

To define back tracking, select the Back Tracking option in the destination object such as Receipt and Shipment, Node, Process, or Model Connector object of the extracted stream.
