• The function to measure the angle (Measuring Angle) between lines and node (Seed) information is

added to the CAD Object Snap function.

2. [Ground] Elastic Link – Fix link End

• The boundary constraints are created automatically at the end of links.

• You can prevent the modeling error using this option and resolve the discomfort which had to set

individual.

• Model > Element > Surface Spring

• Mouse right button click on the OSNAP toggle menu in the bottom of the View > Settings

[Snap Setting > Object Snap]

• The Seed snap is an option if you already input the seed information with the size you want, thegenerated nodes are caught by Snap. Snap option will action during the ‘Geometry > Create/Transform’.

• Command Window > Angle

3. [Slope] Editing the Data of Arc Radius

• You can modify the radius data of arc failure surface (Transform, Expand/Collapse, Rotation) on the

model.

4. [Slope] Review the Critical Height

• Generate an analysis case for each height by dividing the surface automatically for building height.

• You can perform a parametric analysis to consider the critical height for each stage after taking into

account the increase in strength through the soft ground analysis.

• Limit Equilibrium Method > Parametric Analysis > Critical Height

• Selection Filter > Grid for Arc Failure Surface

5. [Dynamic] Improvement the Auto-generate 2D Equivalent Boundary Elements

• This feature creates easily the boundary elements and constraints which are used in 2D equivalent analysis.

It calculates the stiffness automatically by searching the location of free ground dampers. (The meet

parts between the bottom and the transmitting boundary are selected automatically.)

• Model > Element > Auto-generate Boundary Element > Auto-generate 2D Equivalent BoundaryElements

6. [Soft Ground] Slope Coupled Analysis – Connect Water Level

• The water level of slope model is automatically created using the existing water level of 1Dconsolidation model when generating the slope model after 1D consolidation analysis in case of slope

stability analysis considering the increase in strength of soft ground.

• Limit Equilibrium Method > Functions > Water Level

1. [Slope] Cut Failure Surface Boundary and Tension Crack

• You can define the failure surface combining the arc and polygonal failure surface.

• You can calculate the optimal safety factor using the composite failure surface according to the site

conditions and consider to the design by predicting the location where tension crack can occur .

• Limit Equilibrium Method > Boundaries > Cut Failure Surface

[Set Tension Crack ] [Failure Surface with Tension Crack]

[Set Cut Failure Surface] [Define Composite Failure Surface]

• Limit Equilibrium Method > Boundaries > Tension Crack

• In most cases, crack occurs according to the shape of the strata rather than arc failure when the arc

failure surface exists in the bedrock. To simulate this effectively, the function is used to induce destruction

with the shape of composite failure surface by specifying the location of cut failure surface.

• You can do auto-search the location where the tension crack occurs, or define with angle or curve of tension

crack.

• The water pressure which is applied to the tension crack can be considered by defining the degree of

saturation.

2. [Slope] Additional Reinforcement Type and Advanced Option for LEM Analysis

• You can use the Fabric and Anchor type reinforcement which are same function with Slope/W.

• You can adjust the slice segmentation and the reinforcing effect in detail and calculate the reasonable result

of limit equilibrium method.

• LEM > Structural Property > Anchor(LEM)

[Advanced Option for LEM Analysis]

[Define Anchor(LEM)]

• LEM > Structural Property > Strip/Fabric(LEM)

• You can define tensile and pullout force and consider shear force of anchor as well.• The Strip and Fabric types are generally used for the geotextile. In case of considering pullout force,

simplified method takes account only the unit weight and detail method takes account the shape and unit

weight of ground for the upper ground stress of reinforcement.

[Define Strip/Fabric(LEM)]

• Analysis|Design > Analysis Case > Analysis Control > Advanced Option

• If you analysis using the ‘Equal Width’ option when the slope of slice failure surface is grater, the deviation of

the factor of safety for each slices tend to occur significantly.

• You can calculate considering the reinforcement force in the calculation of the equilibrium equations, orcalculate the reinforcement force since the equilibrium equations converge.

• There are two kinds of method considering reinforcement force. The first one is using force and another one

is using stress which acts resistance to the ground.

3. [Slope] Additional LEM Analysis Method

• The detail analysis methods (Spencer, Morgenstern-Price and Sarma(Vertical Slice)) are added in the

LEM analysis.

4. [Seepage] Seepage Rate Option

• You can take account the seepage rate of ground surface when defining the ‘Surface Flux’, and apply the

different seepage rate using the function according to the slope inclination considering the

geometry (slope gradient).

• The review boundary option for seepage face is separated, and you can find the optimum seepage face

within the earliest time.

• Boundaries|Analysis > Boundaries > Surface Flux

[Define Rainfall Intensity/Seepage Rate]

[Define the Function of Rainfall Intensity and Time]

[Define the Function of Seepage Rate and Slope Inclination]

• You need to adjust the rainfall inflow because it differs with the slope inclination, and the seepage rateaccording to the slope inclination can be reflected in the analysis.

RainfallIntensity(q)

• Boundaries|Analysis > Boundaries > Review Boundary

• You can find the exact seepage face using this feature. If the pore pressure > 0, then the pressure head

= 0, and the pore pressure < 0, then the boundaries are automatically deleted.

• The ‘Zoom’ function to adjust the size of object in the post view is added and each layer is registered

separately when you export the result to CAD program.

• Export > CAD file(*.dwg/dxf/dgn)

• Command Window > Zoom

• You can export the result with CAD file using the ‘Main Icon > Export > CAD file’ in the post mode. (Auto-

generation both ‘*.DWG’ with CAD entity and ‘*_ post.DWG’ with result)

• You can create CAD file which contains the detailed results setting such as ‘Deformed + Undeformed

Shapes’ and ‘Mesh Edge’ and the result display by property window. Layers of CAD file are saved

separately considering ‘Deformed + Undeformed Shapes’, ‘Mesh Set’ etc.

2. [Common] Calculation of Result Combination

• You can generate the new result by combining according to the user-defined method.

• For example, you can output the combined result of in-situ result of Ground Module and 2D linear

equivalent analysis result of Dynamic Module.
