Dear friends,

This issue of Groundworks describes some of the activities surrounding our upcoming FLAC/DEM Symposium in Hangzhou, China next year. I believe this is an important opportunity for anyone interested in numerical modeling of geomechanics and the broader field of applied mechanics to get together with experts from around the world to exchange the latest developments and experiences. In conjunction with the symposium, Itasca will also be holding its annual general managers’ meeting. This means that managers from all Itasca offices will be participating in the symposium also, and attendees will have a unique opportunity to meet not only with Itasca software developers, but with those directly responsible for providing consulting and research services. Finally, a number of free workshops will be presented by Itasca specialists on the Friday immediately following the Symposium.

I encourage you to participate in the Symposium by submitting a paper, or at the least registering to attend the symposium and workshops. Registration information will be available soon. Hangzhou is easily accessible for international travelers and we are anticipating a large turnout.

Hope to see you there,

— Loren Lorig, Chief Executive Officer

Symposia

Symposium Logo

Itasca International Inc. will bring together engineers and scientists from around the world to focus on key issues in earth resources engineering and materials handling at the prestigious international FLAC/DEM Symposium on Oct. 22 to 24, 2013 in beautiful Hangzhou, China. The forum will focus on selected current and future applications for Itasca’s state-of-the-art technologies.

Hangzhou

The event is being held in conjunction with the Chinese Society of Rock Mechanics and Engineering (CSRME) Annual Seminar on Numerical and Physical Simulation. Hangzhou — one of the most scenic cities in China — is located about 45 minutes by high-speed train southwest of Shanghai in the West Lake area.

Itasca software products featured at the event include FLAC, FLAC3D, UDEC, 3DEC, PFC, MINEDW, KUBRIX and InSite. Keynote speakers include world-renowned rock mechanics expert and leader, Charles Fairhurst, Ph.D., and Peter Cundall, Ph.D., the prime developer of Itasca software products.

Itasca has issued a call for papers for work related to Itasca software. The papers presented at the symposium will describe these applications in depth, and provide a venue for critical discussion. The deadline for full-paper submissions is February 1, 2013.

KUBRIX

Itasca Consulting Group, Inc. announces the purchase of Simulation Works, Inc. Based in St. Paul, Minn., Simulation Works, Inc. designs and develops the KUBRIX software used by design engineers and researchers in the automotive, aerospace, manufacturing, biomedical, petroleum and electronics industries to automate the more human-intensive and costly aspects of computer-aided engineering.

The purchase of Simulation Works, Inc. will integrate KUBRIX software into Itasca products and services, benefiting clients and promoting expansion into new markets. Itasca’s software range includes the leading numerical modeling software for geomechanical design analyses in earth resources engineering: FLAC, FLAC3D, UDEC, 3DEC and PFC.

KUBRIX is a unique, automatic grid generator (hexahedral, octree and hybrid tet-hex techniques) used in conjunction with CAD software to produce sophisticated computer models. Its capabilities meet the demanding geometrical requirements of rock structure in geo-engineering projects, including non-manifold surfaces and hundreds of materials and intersecting intermittent faults.
