OpenSees User

The OpenSees User pages are intended for users of the OpenSees applications:

1. OpenSees.exe
2. OpenSeesSP.exe
3. OpenSeesMP.exe

These applications are all interpreters which interpret input written in an extended form of the Tcl programming language. The extensions to the Tcl language are for finite element analysis using the classes provided for in the OpenSees Framework.

User Documentation

• Getting Started Manual

The OpenSees Getting Started manual provides a step by step instruction on how to obtain, install, and use OpenSees. For users who have never used OpenSees or a command line interpreter, it is a useful document to read before you go any further.

• Command Manual

The OpenSees Command Manual is now in wiki form. Users and code developers are encouraged to add and correct the manual as the see fit.

The Command Manual details those new commands that have been added to Tcl by the OpenSees interpreters.

In the command manual we only detail those commands added to Tcl for finite element programming.

• Python Scripting

The OpenSees group at Oregon State University has developed an OpenSees module for use in Python scripts. The Python interpreter is newly added to the OpenSees. All commands are in python formats.

• Fluid-Structure Interaction

The OpenSees group at Oregon State University has developed fluid-structure interaction modules for OpenSees based on the particle finite element method (PFEM). The FSI analysis is newly added to the OpenSees for problems such as Tsunami engineering.

• Thermal

The OpenSees Developers Group at the University of Edinburgh is developing and has included thermal capabilities in OpenSees. They have added new Thermal Commands to the interpreter (version 2.4.0+) and provide some Examples on their usage.

• Examples

The OpenSees Examples is a resource for OpenSees users, containing educational and practical examples for beginner through advanced users.

• Cloud Computing

The OpenSees Cloud Computing is a resource for OpenSees users, containing resources on how and where to run OpenSees in the cloud. Users can run on OpenSees in the cloud on machines provided by Amazon-EC2 and resources made available through NEEShub.

• Discovering OpenSees

Discovering OpenSees is a resource for OpenSees users, containing recordings (videos), PPT presentations and accompanying examples from web-based learning series. The topics covered in these learning series are targeted for users of all levels, from the first time users up to advanced users.
