`fracture compute`

command

Syntax

- fracture compute keyword <range>
Primary keywords:

average-trace-length center-density mass-density p10 trace-center-density trace-mass-density percolation

Compute fracture statistics. Various density measures of fractures, filtered by range, can be computed.

- average-trace-length s (3D only)
Return the average trace length, where traces are the intersections between the fractures and the planar geometry set with name s.

- center-density
Return the fracture center density (i.e, P20 in 2D and P30 in 3D).

- mass-density
Return the fracture mass density (i.e., P21 in 2D and P32 in 3D).

- p10 keyword
Return the P10 along the line defined by begin and end, or along the geometry edges defined with the geometry keyword.

- geometry s
P10 is measured along the edges of the geometry set with name s. Cannot be given with the begin or end keywords.

- begin v
Define the starting point of the reference line where P10 is measured. Cannot be given with the geometry keyword.

- end v
Define the ending point of the reference line where P10 is measured. Cannot be given with the geometry keyword.

- trace-center-density s (3D only)
Return the trace center density (i.e., P20), where traces are the intersections between fractures and the planar geometry set with name s.

- trace-mass-density s (3D only)
Return the trace mass density (i.e., P21), where traces are the intersections between the fractures and the planar geometry set with name s.

- percolation
Return the percolation parameter.

Usage Example

The following example illustrates how the `fracture compute`

command can be
used to print fracture statistics (3D).

```
model new
model random 10000
model domain extent -5 5
;Generate fractures using the default template
fracture generate fracture-count 100
;Create a line for p10 calculation
geometry set 'p10line'
geometry edge create by-position (-5,0,0) (5,0,0)
;List some information
fracture compute mass-density
fracture compute center-density
;List the p10 for both the line and by specifying the line ends
fracture compute p10 begin (-5,0,0) end (5,0,0)
fracture compute p10 geometry 'p10line'
```
