New Features in Version 3.0

GALENA Version 3.0 is a fast 32 bit Windows based program containing many new enhancements and features.

Ease of Use

Complete operation from a single program and screen where a model is created, edited, processed and results presented and viewed - one program for all functions, and only one program to start and close.

Easily understood menus, buttons and functions.

Program functions are accessed either from a drop-down menu, buttons on one of the two button-bars or with selected shortcut keys (shown on the drop-down menus).

All surfaces (slope, non-circular failure, phreatic and piezometric), profiles (for material layer definition) and slices (for Sarma analyses) can be mouse-drawn, defined in terms of x/y co-ordinates, or a combination of both.

Preferences can be set to define file save options; to specify a snap accuracy for mouse-draw; and default model file locations.

A background grid is available to assist with model definition.

An improved Tutorial has been included in the Users' Guide, as well as a greater number of Example model files.

The GALENA Users' guide has been re-written and is now also available On-line both within GALENA, and from the Windows menu system.

To allow closer viewing of areas of interest during model definition a progressive zoom function is available.

Speed

Processing and graphics-to-screen speed have been improved and optimised for Pentium processors.

Efficiency

Model files will be Autosaved and a Backup file created (if set in Preferences) before processing each time a model is re-loaded/changed thus saving the user valuable time.

Errors which do not prevent determination of a result are saved to an Error Log for viewing, rather than interrupting a processing stream - if errors were encountered the user will be advised of such in the results dialog for each analysis.

Some of the best features available in DOS programs have been retained, like single-key shortcuts for processing and moving through a model file.

Compatibility

Version 1 and Version 2 data files can be opened and will be automatically converted to Version 3 model files, avoiding re-definition of current models.

Presentation

Text annotation capability has been expanded to allow for more labels with a greater choice of fonts, colours and sizes for placement on the model image at any position and at any angle.

Titles for each analysis can now be specified, in addition to a title for the overall model or project.

Back analysis Multi-Images can be produced where curves representing different Factors of Safety are presented and individually labeled.

Analysis

Automatic tension crack generation at a nominated depth for inclusion at the upper end of all failure surfaces considered in multiple analyses is available - a must for Spencer multiple analyses!

Earthquake Force (Pseudo-static Seismic Coefficient) definition is available.

Negative Ru values can now be defined to assist in modelling of Suction heads (negative porewater pressure regimes).

Profile numbers and the number of points used to define surfaces and profiles have been increased to allow more complex models to be created.

The numbers of External Point Load Forces and Distributed Loads that can be defined have been increased. External Point Load Forces may be set to act at any point and angle on the slope, allowing simulation of bolts or modelling of other forces. Distributed Load Forces can be set to act on any planar part of the slope surface, allowing simulation of vehicle, railway and dragline loads, or overburden loads, as well as complex loads with varying load values throughout the load profile.

The number of individual trial surfaces that can be analysed within each analysis has been increased to over 3,000 and the number of analyses is unlimited.

Included are two improved tools to assist users in their choice of soil and rock strength parameters:

  • RMR (Rock Mass Rating) calculated from input data such as UCS, RQD, Spacing, Water, Condition and Orientation using Bieniawski's method, and thence Hoek-Brown and Mohr-Coulomb strength parameters calculated, and displayed, based on published methods. RMR can also be entered directly, if known.
  • Soil strength parameters displayed in a look-up table, and data input of SPT "N" values and Plasticity Index to estimate phi angles for material property input.

Many other improvements have been made to GALENA, which are not immediately visible to the user, for faster operation and greater ease-of-use. We're sure you'll be pleased with Version 3 for Windows!
