We are pleased to introduce this inaugural issue of Groundworks, a newsletter to communicate with friends and clients the latest information from HCItasca concerning geomechanics and hydrology consulting and software development. We are, to use the publishers’ term, ending the publication run of our previous newsletters, The Source and SoftSpot. We hope this single newsletter will better serve the needs and the interests of our client community. We welcome your comments and suggestions.
—John Markham, Executive Officer

Feature Added: FLAC3D has a new external grid reading capability. Up to now, zones were read from a script file that created them one by one, and rather slowly. This new capability makes it possible to import large externally generated grids at the blink of an eye.

New Pre-release Available Now: The FLAC 5.0 pre-release version is available for download now from the HCItasca web site. Information on the new features in FLAC 5.0 and installation instructions are included with the download. The pre-release is provided to licensed FLAC 4.0 users who have pre-purchased FLAC 5.0. If you have not pre-purchased FLAC 5.0, sales information is available.

New Newsgroup: Itasca has created an online newsgroup for discussion on the use of Itasca software. Initially, the forum is open to discussion of all Itasca codes; we anticipate separating the forum into threads on codes individually as use of the forum demands. Our goal is an enhanced breadth of communication among our code users that can be both useful and informative. Visit the site and let us (and fellow code users) know your thoughts.

 

UpdateAlert:

Updated since 2/1/2004:

 


 

We provide training courses for all of our software products. We offer both general courses and courses that focus on specific geotechnical applications. During 2003 we gave eight courses on FLAC and FLAC3D; most of these courses were designed for individual clients. Our most recent FLAC training was provided as part of a FLAC workshop given for the U.S. Army Corps. of Engineers and focussing on dynamic analysis of embankment dams. Our next software course will be given as part of the SINOROCK2004 conference to be held at the Three Gorges Dam Project Site in China on May 17, 2004. For more information on training see our overview of training opportunities.


 

Itasca will be at Sinorock 2004. The SINOROCK-2004 International Symposium on Rock Mechanics will be held May 18-21, 2004 in The Three Gorges Project Hotel at the Three Gorges Project site on the Yangtze River, Hubei Province, China. Charles Fairhurst of Itasca will be delivering a keynote lecture on the role of numerical methods in Rock Mechanics. In addition, Itasca Consulting Group, Inc. will have an exhibitor's booth at the conference. Please stop by the booth if you are planning to attend the conference.

This is your space!

This section of the newsletter is made available to our code users to share the impressive work they have done using Itasca software. If you would like to submit a contribution, instructions on how to do so are available either from our web site or by emailing the Itasca software department.


 

Q: “Should I upgrade my hardware to run your software?”

A: Upgrades to processors and RAM generally improve calculation time. FLAC, FLAC3D, UDEC, 3DEC, PFC2D, and PFC3D all have a set of suggested minimums; a table of timing tests for various processors is included below the list of minimums. These tables can provide some guidance when selecting a computer system to run your code, but it is up to you decide the balance you wish to strike between computing speed and the price of obtaining it.
