OPNET (version 16.0.A) environment info

Important notes:
  • OPNET v.16.0.A is installed on a Linux server. Get familiar with Linux/CentOS. The following site has links to Unix Toolbox and Tutorials:
        http://www.cyberciti.biz/tips/linux-unix-commands-cheat-sheets.html
  • Before switching to OPNET 16.0.A from other OPNET versions, move the "op_admin" and "op_models" directories to other locations.
  • Use command "modeler". (The command "opnet" will only display a notice about the change.)
  • License server host name for OPNET 16.0.A is "daier". (License server for OPNET 14.0.A is "pluto".)
  • No "ssh/vnc" are available for Linux. Users can only access OPNET 16.0.A from the ESIL Lab.

  • 1. Login to any of the ENSC Sun workstation (Solaris OS) in the ENSC Graduate Computer Room ASB 10802.
    Do not run OPNET without setting your environment first. Type "which opnet" to ensure that there is no path to older versions of OPNET.

  • 2. In order to properly set your environment, add lines to your ".login" ot ".mylogin" file:
        if ( -e /ensc/apps/opnet/16.0.A/sys/unix/bin) then
        setenv OPNETHOME /ensc/apps/opnet/16.0.A/sys/unix
        setenv PATH ${PATH}:${OPNETHOME}/bin
        endif

  • 3. logout and login
    or
    source .login

  • 4. mkdir op_admin
    NOTE: op_admin directory must be directly under the user's home directory and with the correct permissions. (Do chmod 755 op_admin if necessary".)

  • 5. cd op_admin
    Copy to the op_admin directory file env_db16.0 .
    Edit the first line in "mod_dirs" section of the file "env_db16.0" and replace "/ensc/dept1/ljilja/op_models" with the path of your own "op_models" directory.
    NOTE: Make sure that you are the owner of the file "env_db16.0", and that the file has correct permissions. (Do chmod 644 env_db16.0 if necessary.)

  • 6. Run Opnet by typing modeler.

  • 7. If you wish to construct your own models, you need to edit file "env_db16.0" located in the directory "op_admin". Add your own home directory paths in the section "mod_dirs".
    NOTE: Please make sure that your own model directories are listed as the first entries in the file "env_db16.0" in the section "mod_dirs".

  • 8. Ignore the error messages in the command line if Opnet works fine.
    They are from commercial packages that are not available to us.

    REMINDER: Remove any reference to earlier versions of OPNET from your .login file (such as refernces to opnet 14.0.A).
