Summary of Error Codes

When a safety factor cannot be calculated for a slip surface, Slide3 will write an error code to the output file, rather than a safety factor. These error codes are NEGATIVE numbers such as –101, -102, -103 etc. The figure below shows an example of some of the error codes you may encounter while running the analysis.

These error codes are displayed when you select Interpret > Show Error Codes.

The meaning of these error codes are summarized below.

Error Code

Explanation

-97

Factor of safety is out of valid range set by user.

-99

Slip surface intersects through an infinite strength material.

-111

Safety factor equation did not converge.

-114

Surface with reverse curvature.

-115

Surface depth is not within the user-defined min/max values.

-121

Concave failure surface. Only convex slip surfaces are allowed.

-127

Weight of slipping mass is not within the user-defined min/max values.

-128

Volume of slipping mass is not within the user-defined min/max values.

-129

Columns fall outside of the search limits.

-130

Too many failed attempts to create a valid surface. To see most common error types check Interpret>Show Error Codes.

-131

One or more columns had base points that were not within the soil model.

-132

Error in discretization - No active columns.

-133

Too many columns were found to have holes in the soil layers during sampling of soil weight. Perhaps there are holes in the geometry of the model or improperly constructed geometry.

-134

Error in discretization - Too few active columns.

-135

-137

Axis of symmetry is not passing through search limits.

-138

Error in discretization - Too few active columns.

-139

Non-spherical Auto-Refine Search not supported. Change the Surface Type to Spheres in the Slip Surface.

-140

None of the grid points in Auto Refine Search produced a valid slip surface. To see a list of error codes check Interpret > Show Error Codes.

-141

Surface elevation below external geometry. You may try external geometry composite surface option.

-142

Wedge persistence exceeding the user-defined limit.

-143

-145

Failure mass has invalid boundary columns.

-146

Error calculating applied force polygons.

-147

Failure mass contains internal regions without columns.

-148

Internal intersection of slip surface with ground surface detected.

-149

Slip surface was clipped vertically by a weak layer in a region of compression. Such a surface cannot be evaluated using Limit Equilibrium. For more information, see Help Documentation on weak layers.

-150

Surface intersects outside search limits.

-151

Surface does not intersect specified Intersects search limit.

-152

Surface intersects outside search limits (edge of slip surface).

-153

Surface touches the edge of model limits.

-154

Surface violates surface-defined slope limits.

-160

General block model error.

-161

Slip surface touches an undefined region within a block model.

-162

Too many weak layers touching this slip surface. Consider suppressing or combining some weak layers, or using Surface Options > Always snap to highest.

-200

Factor of Safety <= min iteration value. Could mean 0 Normal/Shear resistance along part of the slip surface.

-402

Unable to compute factor of safety due to symmetric forces/moments cancelling out each other along X/Y axes.

-403

Could not compute initial failure direction, possibly flat ground surface.

-404

Computed lambda values outside the specified range in the advanced project settings.

-405

Nonlinear equation solver failed to find a solution.

-406

Failed to compute factor of safety.

-407

Iteration of the intercolumn lambda value failed to find a solution.

-408

Iteration of the failure direction failed to find a solution.

-409

Failed to compute a shear force given a normal force.

-410

-413

A column base angle exceeds the limit in the advanced project settings.

-414

Error computing the weight of a column.

-415

RSPile analysis of reaction force did not converge for this slip surface with the given soil displacement. Consider reducing the displacement to improve convergence.
