Q-VT Release Notes

Release Notes

TBS 2018, Release 1.75 (New)
  • Advanced GUI for surface module
  • Other smaller changes


September 2017, Release 1.7 (New)
  • Chemistry tab: Import chemistries from QDB
  • Chemistry tab: Calculate Arrhenius parameters from user-provided cross sections
  • Chemistry tab: initial GUI for surface module for basic settings
  • Chemistry tab: reactions added by the user can now be stored in a local database

  • Updated species and reactions databases
  • Minor bug fixes


February 2017, Release 1.6
  • Chemistry tab: You can now connect to QDB and search for reactions involving specified species from your chemistry. This requires an internet connection, a QDB gold account, and a QDB API key. To obtain a QDB API key, please contact support@quantemol.com
