An OpenSees Editor - TclEditor(download)
TclEditor is an editor for creating and running OpenSees scripts on a machine running the Windows operating system. It was developed at Stanford by Rohit Kaul and Prof. Gregory Deierlein, who would welcome your comments/suggestions. Until an installer program is provided, you should follow these instructions to install TclEditor:

1. Download the zip file and save to disk
2. Unzip the file.  This will create a directory called tcleditor.  After you unzip the files you should copy the tcleditor directory into the root directory of the C: drive on your computer. (Note  be sure to copy this directory to the upper level root directory of the C: drive).
   
3. Update the first line of the file C:\tcleditor\tcleditor.conf to correct path for the opensees executable. or just copy the opensees executable to c:\tcleditor\bin and rename it to openSees.exe
4. Run the file TclEditor.exe that is located in C:\tcleditor\BIN directory.
   
5. Read the ReadmeFirst.tcl in the C:\tcleditor directory for more information on installation.  Under the installation instructions, you will see how to make changes to your specific path definitions in the tcleditor.conf.
   
6. To see some examples, open some of the *.tcl files in the C:\tcleditor\ExampleScripts directory.

An OpenSees Graphical Post Processor - OSP(download)
OSP is a Graphical User Interface for post processing OpenSees results and viewing OpenSees input files. OSP runs under Windows 9X, NT, and 2000. It contains an editor where linked input files can be viewed and edited, then seen graphically. Time histories can be played and viewed in real time and .avi files can be exported. Nodal displacement and member force time histories can be traced while simultaneously seeing the global system behavior. This program is most useful for complex 3D models. It was developed by Charles Chadwell as part of a Long Span bridge research project.
To install, just double click or run the downloaded executable. Be warned, that this executable may modify certain operating system files for which we take no responsibility. Help files ship with the installation program but if you have any questions, comments, or concerns regarding the installation or execution, please contact Charles Chadwell for help.
