QEC Release Notes

Release Notes

March 2020, Release 1.1 (new)

1.1 New Features

  • It is now possible to turn off the long-range moments in the outer region of the calculation. This can be used to approximate the electron scattering in the condensed phase. Information on how to do this has been added to the topic of Advanced R-matrix options in the Setting up Cross Section Calculations section.
  • Interactive help pages can be accessed from the Help menu from inside the Quantemol-EC application, including the full documentation (Documentation), help on each page of the setup procedure (Help on this page), and searchable content (Search). The tutorial video for Quantemol-EC can now also be accessed from the Help menu, by clicking on Tutorial. Additionally, the Help menu has an About page to clearly show you which versions of Quantemol-EC, Molpro and the R-matrix routines are being used.
  • It is now possible to save optimized geometry files in .xyz formats, making it easier to restart calculations. More information on this can be found in the section Geometry Optimization.
