ERROR 24
One of the x-coordinates of the termination range lies to the RIGHT
of the defined ground surface profile. This range must EXIST within
the defined geometry. Please make sure that the value of the right
point is less than the right x-coord of the last surface boundary.
ERROR 25
It appears that the first termination point does NOT correspond to
the LEFT side of the termination range. These two values must be
specified in a left-to-right sequence. Please check the data for
surface generation using either circular or non-circular surfaces.
ERROR 26
The right limit of the initiation range is located beyond the right
limit of the termination range. Due to this overlap, surfaces that
start from the initiation range cannot extend into the specified
termination range. Please check the initiation/termination ranges.
ERROR 27
An initiation point is located below the imposed elevation depth
limitation. Either the initiation range or the depth limitations
must be changed to enable the successful generation of trial failure
surfaces. Please correct the data before retrying the analysis.
ERROR 28
In automatically generating a failure surface, it has been found that
more than 100 points are needed to define this surface. The program
is limited to a maximum of 100 points. To meet this criterion,
please INCREASE the specified length of the line segments.
ERROR 29
The program has made 200 attempts to generate a single trial failure
surface. It is possible that the search limitations are either too
restrictive, or they actually prevent successful generation of a
trial failure surface. Check and revise the search limitations.
ERROR 30
The angle specified as the LOWER angular limit for surface generation
is larger than the angle specified as the UPPER limit. This is not
correct. Please check the data for a possible reversal of these
values before retrying the analysis.
