fracture aperture
command
Syntax
 fracture aperture keyword ... <range>

Assign apertures to fractures. Apertures can be used during contact model assignment (with the
fracture contactmodel
command), for connectivity distance calculations (with thefracture connectivity
command) and with the DFN range element. dfn s
Limit aperture assignment to the DFN with provided name.
 fish s a_{1}...a_{n}
Apertures are assigned via the userdefined FISH function s with arguments . This function is called for each fracture and must return a floating point value corresponding to the fracture aperture.
 gauss fm fs
Draw apertures randomly from a Gaussian distribution with mean fm and standard deviation fs.
 limits fmin fmax
Apertures fall within the range [fmin, fmax], where fmax is greater than or equal to fmin. By default, fmin = 0 and fmax = +∞.
 lognormal fm fs
Draw apertures randomly from a lognormal distribution with mean fm and standard deviation fs.
 uniform
Draw apertures randomly from a uniform distribution within the given limits as defined by the limit keyword.
Usage Example
The following example illustrates how the fracture aperture
command can be used
to assign apertures drawn from a number of distributions.
model new
model random 10000
model domain extent 5 5
;Generate fractures using the default template
fracture generate fracturecount 1000
;Set the apertures
fracture aperture lognormal 0.1 10
program return
