Copyright 1999-2000 VA Linux Systems, Inc. http://neesforge.nees.org NEESforge Project News Highlights http://neesforge.nees.org/forum/forum.php?forum_id=200 OpenFresco is a software framework that facilitates local or geographically distributed deployment of hybrid simulation. The Open-source Framework for Experimental Setup and Control (OpenFresco) carries out in a convenient, modular and standardized manner those additional functions needed by structural analysis software (such as Abaqus (TM), LS-Dyna (TM), Matlab (TM), OpenSees, UI-SimCor, and Zeus-NL) to work with laboratory equipment to perform hybrid simulations. Based on a systems analysis of the operations performed during hybrid simulations, OpenFresco provides independent modules for connecting to analysis software, specifying test setups, interacting with control and data acquisition systems, and accessing communication protocols. Experimental control and data acquisition modules are available for popular systems manufactured by dSpace (TM), MTS (TM) (STS and FlexTest systems), National Instruments (TM), SCRAMNet (TM), Shore Western (TM) and others. OpenFresco provides modules for experimental setups for many common one-, two- and three-dimensional test configurations. Being object-oriented and open source OpenFresco’s capabilities can be easily extended and adapted to meet project specific needs, including complex configurations of actuators and test setups. OpenFresco is computer and operating system independent. OpenFresco has been extensively used for local and geographically distributed tests within North America and between the U.S. and Asia. Nearly 20 major improvements have been included in Version 2.5. Notable among these are up to three times faster execution of geographically distributed tests, improved stability, secure communications via OpenSSL, applicability to a broader range of equipment control systems, the ability to simulate a hybrid test incorporating a numerical model of the complete test specimen, and numerous user requested technical enhancements. A self-installer is provided to facilitate installing OpenFresco components on Windows platforms. Extensive documentation accompanies the new release, including an installation and getting started manual, a detailed command-language manual and several example manuals. OpenFresco Version 2.5, along with its documentation and user forums for requesting and commenting on features can be obtained at: http://openfresco.neesforge.nees.org/ OpenFresco Andreas Schellenberg Tue, 15 Jan 2008 2:04:32 GMT http://neesforge.nees.org/forum/forum.php?forum_id=103 With the support and collaboration of NEESit and NEESinc, the MUST-SIM research team at Illinois has developed and thoroughly tested a general purpose Multi-Site, Multi-Platform, Distributed Hybrid Simulation open-source software package. We are pleased to offer the package, UI-SIMCOR, to the community and support its use and further development. SIMCOR’s source code, documentation, and examples can be downloaded from NEESforg at http://neesforge.nees.org/frs/?group_id=21. SIMCOR is not based on any particular analysis environment. It is fully compatible with ZEUS-NL (MAE Center analysis platform), OpenSees (PEER Center analysis platform), Fedeaslab (Matlab FE package from Prof. Filipou), Vector2 (RC detailed analysis program from Toronto), and Abaqus (widely used commercial package). SIMCOR is written in matlab and is very easy to download, use, and modify. We are willing to consider developing interfaces to users' favorite FE package and willing to support users in developing interfaces to their equipment sites. The interfaces are very simple and examples are well documented. Moreover, SIMCOR fully supports the following communication protocols: (i) NEESgrid Tele-operation Control Protocol (NTCP), (ii) raw TCP-IP, and (iii) NEESit’s new secure NEES Hybrid Simulation Communications Protocol (NHCP). SIMCOR has been verified by analysis, physical testing, and hybrid testing, by running many examples with University of Lehigh, RPI, UC San Diego, and UC Berkeley. Its development and reference applications have been published in journals; hence it has been rigorously peer-reviewed. Please refer a flyer describing the features of SIMCOR. The flyer is uploaded on Documentation folder. For general inquiries, contact Prof. Spencer at bfs@uiuc.edu. For technical inquires, contact Oh-Sung Kwon (okwon2@uiuc.edu) or Kyu-Sik Park (kspark@uiuc.edu).

Any finite element analysis software that allows for the addition of elements can now be used with OpenFresco 2.0. The corresponding installation and examples manual is available under the “Docs” section (tab at the top) of the OpenFresco page. OpenFresco Andreas Schellenberg Wed, 03 Jan 2007 4:40:43 GMT http://neesforge.nees.org/forum/forum.php?forum_id=98 The manual for OpenFresco version 1.0-beta is now available under the "Docs" tab. In addition, some conference papers are posted there as well. OpenFresco Andreas Schellenberg Thu, 30 Nov 2006 4:24:38 GMT http://neesforge.nees.org/forum/forum.php?forum_id=20 The first NEESforge user survey is posted. Please use the following link to access it: http://neesforge.nees.org/survey/survey.php?group_id=6&survey_id=1 NEESforge Wei Deng Sun, 04 Dec 2005 4:41:43 GMT http://neesforge.nees.org/forum/forum.php?forum_id=7 NEESit is pleased to announce NEESforge, the community code repository for the Network for Earthquake Engineering Simulation (NEES) community. The purpose of this site is to enable all members of the NEES community to make their software available publicly, as well as to provide a means to view software other NEES sites have developed. This is the place to share any useful code, and to find developers to collaborate on your software projects. NEESforge is based on Gforge, a Collaborative Development Environment which provides a centralized interface to manage and track software projects. NEESforge will compliment the NEES community and the nature of distributed development efforts with tools that are already familiar and easy to use. NEESforge provides utilities to foster collaboration and development, including: * Source repositories (CVS or Subversion) * Mailing lists * Discussion forums * A "Tracker" for tracking bugs and change requests * Project management for assigning tasks to developers * News announcements * Document and release management NEESforge Wei Deng Sat, 03 Dec 2005 7:06:45 GMT
