The best way to run OpenSees is to actually use the DOS terminal application. Before you do we strongly advise that you set the PATH variable to the location in which you place the OpenSees.exe. You can place it anywhere on your system. c:\Program Files\OpenSees\bin is where I place it.

To set the PATH Variable on Windows you follow the instructions below:

  • Windows 8
  1. Drag the Mouse pointer to the Right bottom corner of the screen
  2. Click on the Search icon and type: Control Panel
  3. Click on -> Control Panel -> System -> Advanced
  4. Click on Environment Variables, under System Variables, find PATH, and click on it.
  5. In the Edit windows, modify PATH by adding the location of the class to the value for PATH. If you do not have the item PATH, you may select to add a new variable and add PATH as the name and the location of the class as the value.
  6. Close the window.
  7. Open a DOS window, and type OpenSees. If it works you were successfull.
  • Windows 7
  1. Select Computer from the Start menu
  2. Choose System Properties from the context menu
  3. Click Advanced system settings > Advanced tab
  4. Click on Environment Variables, under System Variables, find PATH, and click on it.
  5. In the Edit windows, modify PATH by adding the location of the class to the value for PATH. If you do not have the item PATH, you may select to add a new variable and add PATH as the name and the location of the class as the value.

  5. Open a DOS window, and type OpenSees. If it works you were success


Once the PATH variable has been set, you can run OpenSees from whatever directory you are in in the Windows Terminal Application. So start a DOS window.

Then use the cd command in the window to move to the directory where your tcl files are located.

There are then three ways that OpenSees/Tcl commands can be executed:

Interactive

Commands can be input directly at the propt, as shown in the figure (Win32 version):

Execute Input File at OpenSees prompt

This method is the most-commonly used one.
An external file containing the input commands can be generated a-priori (inputFile.tcl) and be executed at the OpenSees prompt by using the Tcl source command. The generation of the input script files is presented in this chapter.
In the figure below, the user types the following command at the OpenSees prompt:

source inputFile.tcl

The file execution is shown in the figure (Win32 version):

Batch Mode

The previously-created input file containing the Tcl script commands necessary to execute the analsis can also be executed at the MS-DOS/Unix prompt, as shown in the figure (Win32 version):

In the figure below, the user types the following command at the DOS prompt:
