You can specify
effective radius (ro)
using one of the following five options:
1.
Manually –
by
entering value in the text box "Radius".
2.
Width / Length > 0.5 (areabased) –
radius for
nonelongated layouts is calculated using area of the pit (F) by
the formula:
3.
Width / Length > 0.5 (perimeterbased) –
radius for
nonelongated layouts is calculated using perimeter of the pit
contour (P) by the formula:
4.
Width / Length <= 0.5 –
radius for
elongated layouts is calculated by the formula:
d – pit length,
m;
b – pit width,
m; η
– it
is defined by a polynomial: for b / d <= 0.5:
5.
Complex layout –
radius is
calculated using the formula:
n – number of
polygon segments;
ri
–
distance from pit center to vertex of polygon
