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.

• Examples Manual

The OpenSees Examples Manual contains examples on how to create models and perform simulations on those models.

It has examples ranging from simple single element linear models to complex 3D nonlinear fiber models.

These examples are intended only to show the usage of the commands available in OpenSees. They are not necessarily examples showing the best of practice.
