July 2009: Multiple Time Step Rapid Drawdown
Perform a rigorous stability analysis by understanding it as a process,
not a factor of safety at one instance in time.

December 2005: Establishing Insitu Stresses with SIGMA/W. One of the more
important aspects of any stress-deformation analysis is establishing the insitu stresses. Learn
how to
do a "gravity turn-on" analysis with SIGMA/W. Also in this edition,
we congratulate Dr. John Krahn on being awarded the R.F. Legget Medal,
and we explain how we've made it easier to download your license files.
- November 2005:
Sensitivity Analysis with SLOPE/W.
Learn how a simple sensitivity analysis can be used to help obtain a better
understanding of the influence of particular parameters in a slope
stability analysis.
- October 2005:
Display of Most Critical Slip Surfaces.
In the early days, the only way to portray a summary of all the
safety factors was to contour them on a grid of rotation centers.
With today's sophisticated software, there are now other more
convenient and meaningful ways which can help interpret
slope stability results. Also in this issue, a review of the
5th Annual Calgary Geotechnical Modeling Workshop.
- September 2005:
Reflections on Ethiopia.
John Krahn reflects on his recent trip to Ethiopia to lead a modeling workshop.
Also in this issue, watch a video to learn when and how to use function
estimation in SEEP/W.
- August 2005:
SLOPE/W Slip Surface Optimization.
Learn how SLOPE/W can distort your slip surface to find the lowest factor of safety.
Also in this issue, John Krahn travels to Ethiopia to provide engineering mentorship.
- July 2005:
Demystifying a transient analysis.
Some people panic when they hear the words "transient seepage analysis." However, if you
feel your steady-state seepage results do not reflect what you believe to be happening in
the ground, it is likely because you are trying to represent a transient condition with a
steady-state solution.
- June 2005:
Serving up new changes on the website... Significant changes are being made to the
geo-slope.com website to better serve you. Read about some of the initiatives here, and how Microsoft is
interested in what we're doing.
-
May 2005: Read about the influence of water flow on ground freezing. Also in this
issue, the 5th Annual Calgary Geotechnical Modeling Workshop is only a few months away--read the
details and register early to save your spot.
-
April 2005: The coastal landslides in California in the U.S. and British Columbia
in Canada were in the news around the world in February. Why did they happen? This edition of
Direct Contact uses SEEP/W and SLOPE/W to explain some of the factors.
-
March 2005: GeoStudio's power lies in the integration between its products.
Watch a video showing SEEP/W and SLOPE/W working together. Also learn about upcoming Geotechnical
Modeling workshops in the UK and in Calgary. This edition congratulates our CEO,
John Krahn, on being awarded an EIC Fellowship.
-
February 2005: John Krahn describes how to analyze geofabrics with SLOPE/W.
-
January 2005: A message from the CEO: Numerical Modelling - Prediction or Process?
And visit us at Geo-Frontiers 2005 in Texas!

showing the benefits of unstructured meshing and how GeoStudio 2004 saves you time and effort by
ensuring mesh compatibility.
-
November 2004: Watch a movie demonstrating the power of regions in SLOPE/W 2004,
and learn about an important update to GeoStudio 2004.
