~SLPIN

 

~SLPIN, N1, N2, N3, KCN

Capture an ANSYS model through nodes to perform a slope stability analysis

PREP7: GEOTECHNICAL MODULE: Slope stability

N1

Node 1 that defines the surface (initial point).

N2

Node 2 that defines the surface (final point).

N3

Node 3 that defines the surface (intermediate point to specify the path).

KCN

Coordinate system. By default, the active CSYS will be taken. The earth weight is calculated in the direction of the negative Y-axis.

Notes

- The following Plane elements are admitted:

- MESH200 (KeyOpts 4, 5, 6, 7): Must be in the XY plane or at least, they have to be parallel to it.

- PLANE2, PLANE35, PLANE146: 6-node-triangular plane elements.

- PLANE13, PLANE42, PLANE55, PLANE67, PLANE162, PLANE182: 4-node rectangular plane elements.

- PLANE53, PLANE77, PLANE82, PLANE121, PLANE145, PLANE183: 8-node rectangular plane elements.

- All elements must be linked, making up a surface with a single boundary. Holes within earth are not admitted, but they can be filled with “flimsy” material.

- The N1, N2 and N3 nodes define the surface according to the following rule: the surface covers the distance between node N1 and node N2, going through all the nodes of the “half boundary” that contains N3. Nodes and elements must be selected.

- The ~SLPIN command creates a “jobname.SLP” file, where all data are saved, not only the input data, but also the results.
