fracture-class {RGeostats} R Documentation

## Class "fracture" Set of Fault and Fractures

### Description

This class contains the definition of a set of deterministic faults and random fractures, used to fill a 2-D space, subdivided into rectangular layers. The fractures belong to several families (defined as faults, joints, veins, ...): they will be called fractures in this document.

This model is a 2-D prototype which will be expanded to 3-D in the future.

### Objects from the Class

Objects can be created by calls of the form `new("fracture", ...)`.

### Slots

`xmax`:

Object of class `"numeric"` Horizontal extension of the field

`ymax`:

Object of class `"numeric"` Vertical extension of the field

`deltax`:

Object of class `"numeric"` Horizontal dilation of the field

`deltay`:

Object of class `"numeric"` Vertical dilation of the field (negative ordinate only)

`mean`:

Object of class `"numeric"` Mean of the Thickness distribution. In addition, this parameter sets the minimum for the thickness of a layer (mean / 10)

`stdev`:

Object of class `"numeric"` Standard deviation of the Thickness distribution

`fams`:

Object of class `"list"` List of definitions of `ffam-class`

`faults`:

Object of class `"list"` List of definitions of `ffault-class`

### Methods

\\$

`fracture\$parameter` is used to query the value of `parameter` from `fracture`:

• nfamilies : Number of families in the `fracture-class`

• nfaults : Number of `ffault-class` in the `fracture-class`

• xmax : Field extension along the horizontal direction

• ymax : Field extension along the vertical direction (calculated as the sum of the layer thicknesses

\\$<-

`signature(x = "fracture")`: ...

show

`fracture.print`

print

`fracture.print`

plot

`fracsimu.plot`

Other functions are available, such as:

• `fracture.input` Define a `fracture-class` interactively

• `fracture.print` Print the contents of a `fracture-class`

• `fracture.read` Read the contents of a `fracture-class` from a neutral ASCII File

### Examples

```showClass("fracture")
```
