v1.7

In this new release, the OWCF has been upgraded with the following:

• The OWCF is now more Windows-friendly. The OWCF tests can now be run on Windows without producing errors
• The installation of the OWCF has now been made even easier with an installation script install_OWCF.jl. To install the OWCF, the user simply types julia install_OWCF.jl and follows the instructions. To manually specify the path to a Python executable is no longer needed
• The README has been updated to be more pedagogical and explain the requirements for Julia and Pythons versions and packages in detail. The README is now considered to be a better guide for installation than the OWCF .pdf manuals.
• The OWCF apps have been re-written as Jupyter notebooks. This is to fascilitate robustness and long-term support. In addition, the app documentation has been enhanced
• The support for using the OWCF on SLURM computational clusters has been switched from ClusterManagers.jl to SlurmClusterManager.jl, ensuring long-term support
• Several bug fixes have been made
• The bounds for the regularization strength can now be customized when using the solveInverseProblem.jl OWCF tool
• The robustness for loading magnetic equilibrium data has been improved

v1.6

The OWCF has undergone major upgrades since the last version. The most important changes include:

• Use Julia v1.11.6 (the latest stable release as of 15th of July 2025)
• Possibility to truly take finite Larmor radius (FLR) effects into account when computing synthetic measurements
• The OWCF tests, which ensure correct functionality after installation/development
• Use electromagnetic wave heating in the ion cyclotron range of frequencies (ICRF) when reconstructing the fast-ion distribution by solving an inverse problem with the OWCF/solveInverseProblem.jl tool
• Updated README
• Robustness upgrades for many of the OWCF tools
• Bug fixes
• The possibility to include plots of the results as output of several of the OWCF tools

These changes unfortunately make old start files unusable. So please upgrade your start files by using the templates in the OWCF/templates/ subfolder.

Also, please upgrade your Julia to v1.11.6, if you have not already.

A detailed list of all the changes can be found below.

Enjoy!

v1.4.0

The inverse problem solving tool of the OWCF. It is a first working version, and includes established methods such as 0th and 1st order Tikhonov regularization, collision physics regularization, non-negativity constraint etc. The tool can be used to reconstruct fast-ion distributions of any dimensionality between (and including) 1D and 6D. The user can specify measurement regions to exclude from the problem, use TRANSP distributions to rescale weight functions to have WF match experimental data, specify thresholds for measurements and signal noise and more. The tool may also be used to solve inverse problems in any coordinate system, such as energy-pitch, v_parallel-v_perp, orbit space, constants-of-motion space etc. Plots of the L-curve, S vs WF and reconstructed fast-ion distribution can be requested to be saved as .png files as well as a .gif file. The documentation is currently at a basic level and will be successively improved in the next versions.
