Crack Information
You want to:
create first
create additional
crack.
Crack Type:
Circular or Elliptical

Crack Name:
Names containing spaces must be in quotes
X1
(Dip-Direction)
Half Length:
X1/X2
Height/Width
# of Conc. Rings:
The crack is subdivided into concentric rings. If you want to model the whole crack as one element, enter 0 for a rectangular crack or 1 for an elliptical crack.
Crack Location
Crack Coord. Sys:
Placement:
Place the coordinate system at the center of the crack
Create the crack in the first quadrant
Create the crack in the second quadrant
Create the crack in the third quadrant
Create the crack in the fourth quadrant
