This is to <br />limit the calculation of extremely high safety <br />factors if the driving force is very small <br />(0.1 is an arbitrary number). <br />-1000 = No valid slip surfaces are generated <br />at a grid center. Unable to draw a surface. <br />-103 =Two surface /slope intersections, <br />but one or more surface / nonslope external polygon <br />intersections lie between them. This usually occurs <br />when the slip surface extends past the bottom of the <br />soil region, but may also occur on a benched <br />slope model with two sets of Slope Limits. <br />-107 =Total driving moment or <br />total driving force is negative. This will occur <br />if the wrong failure direction is specified, <br />or if high external or anchor loads are applied <br />against the failure direction. <br />List of All Coordinates <br />Search Grid <br />1595.362 984.794 <br />3106.429 984.794 <br />
