Identifications: 1DEL (1D fractures), 2DEL (2D fractures)

Model type: 1K, 2K

With the help of these data, the 1D and 2D fracture elements are defined by specifying the nodes which form the fractures. The fractures can be numbered in any order.

 

Each fracture definition contains the fracture number and the two to four node numbers which form the fracture. In the case of 2D fractures with only three corners, the fourth node is 0. Each line in the model - or 3D file (*.3d) can contain two complete fracture definitions.

 

Columns 1 - 6: no. 1st fracture

Columns 7 - 12: 1st node no. 1st fracture

Columns 13 - 18: 2nd node no. 1st fracture

Columns 19 - 24: 3rd node no. 1st fracture (only for 2D fractures)

Columns 25 - 30: 4th node no. 1st fracture (only for 2D fractures)

Columns 37 - 42: no. 2nd fracture

Columns 43 - 48: 1st node no. 2nd fracture

Columns 49 - 54: 2nd node no. 2nd fracture

Columns 55 - 60: 3rd node no. 2nd fracture (only for 2D fractures)

Columns 61 - 66: 4th node no. 2nd fracture (only for 2D fractures)

 

Within a line, either the 1st or the 2nd fracture definition can be deleted without completing the columns again. One-dimensional fractures (1DEL) can currently only be created or shown with the program KLUFTI.
