First, the BTM ranks tracer elements according to their food-to-soil (F/S) ratios, defined as the mass of the tracer element ingested from food over a 1-d period divided by the mass of the tracer element in 1 g of soil.

In short, SIR data based on each tracer element were characterized by a skewed distribution, high variation, and some outliers.

If a tracer element moved past the flow front, the element was moved closer to the wall and its axial position was set to be just behind the flow front.

In other words, a new set of tracer elements was inserted every time the melt front advanced by 2% of the nodes in the axial direction.
