# Launching OPTFEKO (Linux)

Use the most suitable option for launching OPTFEKO in Linux.

Launch OPTFEKO using one of the following options:
• On the Solve/Run tab, in the Run/Launch group, click the  OPTFEKO icon.
• Launch OPTFEKO from the command line in a terminal environment.
1. Open a command terminal. Source the script initfeko using the absolute path to . /home/user/2022.0/altair/feko/bin/optfeko
2. In the terminal (assuming the model with file name dipole.cfx is to be optimised) type the following command
optfeko dipole
and press Enter.
Note: The above steps will launch OPTFEKO without any special settings. It is also possible to use parallel processing for optimisation.
