I have posted a YouTube video showing how to perform an OpenSees simulation using this tool. An improved version will be available soon. The OpenSees GUI applications, BuildingTcl and OS Navigator, are also available to run.
Try them out, registration and use of the machines are free!
The goal of the OpenSees development is to improve the modeling and computational simulation in earthquake engineering through open-source development.
OpenSees is under continual development, so users and developers should expect changes and updates on a regular basis. In this sense, all users are developers so it is important to register. More information on Open Source is available.
OpenSees has been selected as the simulation component for the George E. Brown, Jr. Network for Earthquake Engineering Simulation and is being sponsored by NEEScomm . NEEScomm provides support for the ongoing maintenace of OpenSees and support to integrate OpenSees with the IT and EOT resources that NEEScomm makes available to the earthquake engineering community.
