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 />-109 = Soiltype for slice base not <br />located. This error should occur very rarely, <br />if at all. It may occur if a very low number of <br />\,• slices is combined with certain soil geometries,
