fracture.near
Syntax
- frac = fracture.near(vp<,frad><,dfn>)
Find the closest fracture to a point. If frad is specified, then the search radius is limited. If dfn is not given the calculation is undertaken over all fractures of all DFNs.
Returns: frac - fracture pointer
Arguments: vp - position
frad - optional search radius
dfn - optional DFN pointer
Usage Example
The following example illustrates how fracture.near
can be
used.
model new
model random 10000
model domain extent -5 5
;Generate fractures using the default template
fracture generate fracture-count 100 dfn 'first'
fracture generate fracture-count 100 dfn 'second'
; find the closest fracture to the center

local f2 = fracture.near(pt1,1e5,dfn.find('second'))
