Registration Open for OpenSees Days 2011 on August 22-23

The OpenSees Development Team is pleased to announce OpenSees Days 2011 – two full days of User & Developer Workshops! This year’s event will occur on August 22-23, 2011 at UC Berkeley’s Richmond Field Station.

The OpenSees User Workshop will occur on August 22nd. This annual one-day workshop on will focus on how to use OpenSees, and will include more hands-on activities than included in previous years. This workshop is intended for beginning and intermediate users. This workshop will introduce users to the Tcl scripting language, as well as basic modeling and analysis techniques using OpenSees.

The second day of OpenSees Days 2011, August 23rd, will cover Advanced Tools and Topics. This one-day workshop will include presentations on advanced topics including parallel & cloud computing, reliability and sensitivity analysis, and optimization. The afternoon session will focus on the development of basic GUI interfaces to OpenSees.

At the conclusion of the event, participants will choose the winner of this year’s OpenSees Challenge. The OpenSees Challenge will be awarded to the developer who develops the best-judged OpenSees powered tool running on NEEShub. For more information, or to view the challenge rules, visit:

Students, researchers, and practitioners are welcome to attend any of the OpenSees Days workshop sessions. Registration is free, lunch is provided, but space is limited to the first 100 applicants. Registration closes on August 19, 2011.

The Open System for Earthquake Engineering Simulation (OpenSees) is a software framework for simulating the seismic response of structural and geotechnical systems. OpenSees has advanced capabilities for modeling and analyzing the nonlinear response of systems using a wide range of material models, elements, and solution algorithms. OpenSees has been developed as the computational platform for research in performance-based earthquake engineering at the Pacific Earthquake Engineering Research Center. OpenSees is also the simulation component for the NEESit since 2004. For more information about OpenSees, visit:
