Line (Shapes)

There are two types of line objects which can be used in the model design:

Edge (Shapes|Line|Edge)

Define an edge (i.e. a straight boundary) in a rock mass. The geometrical properties as well as the boundary conditions can be defined and altered in View (Object Properties). The edge can also be repositioned and resized by selecting and dragging the object using mouse.

An edge is defined by giving the coordinates of the start and end points. The start and end points have to be arranged in such a way that the negative side of the edge is the rock mass, as shown below.

This command can be selected by clicking the speed button on the speed bar.

Fracture (Shapes|Line|Fracture)

Define a fracture in a rock mass. The geometrical properties as well as the mechanical properties of the fracture can be defined and altered in View (Object Properties). The fracture can also be repositioned and resized by selecting and dragging the object using mouse.

A fracture is defined by giving the coordinates of the start and end points. The definition of a fracture is not sensitive to the sequence of the start and end points.

This command can be selected by clicking the speed button on the speed bar.
