Define
the slip surface of the virtual fracture arc using the
grid point of the arc center and radius where the tangent
line to the arc is located.
Specify
the rectangular grid area where the arc center can be
located using 3 points (reference point x,y).
The
center count x, y is the number of divisions in the grid
area.
For
example, entering a center count of 5,4 creates 5 x 4
= 20 arc center points.
The
radius where the tangent line of the arc is located can
be set using [Method using Tangent Line of Circle] or
[Method using Length and Range of Radius].
Method using Tangent Line of Circle
Directly
specify the rectangular area where the tangent line is
located on the work screen using [Draw Range]. The number
of radius divisions divides the rectangular area by that
number and the tangent direction of the arc radius domain
can be changed using [Change Tangent Direction].
Method using Length and Range
of Radius
Directly
input the length of initial circular radius, increment
for circle radius and number of increments for circle
radius.
Boundary Set
Register
the set constraint conditions of the desired boundary
set. The user can specify the name of the boundary set.

Define an circular
virtual slip surface. The virtual slip surface is a boundary
condition used in slope stability analysis. The virtual
slip surface can only be set when the analysis setting
is for 2D models.
