Surface Generation Method
The Surface Generation Method in the Slip Surface Options dialog allows you to choose one of two options:
- Search Methods
- User-Defined Surfaces
Search Methods
The Search Methods option allows you to generate slip surfaces by choosing one of the Search Method options (e.g. Cuckoo Search, Particle Swarm, Grid Search) to search for critical slip surfaces with the minimum safety factors. This is the default Surface Generation Method which will be used most of the time.
User-Defined Surfaces
The User Defined Surfaces option requires that you define slip surfaces using Add User-Defined Slip Surface. This allows you to define and analyze individual spherical, ellipsoidal or general slip surfaces with user-defined parameters.
If you choose User Defined Surfaces, you can still apply the following options:
to the user-defined surfaces.
