Q-N Release Notes


Release Notes

[expand title=”January 2018, Release 6.0 (New)”]

  • Use of Molpro Orbitals for calculation of the wavefunctions not only ground state but excited state electron configuration giving more precise results for inelastic collision calculations (the feature requires user have a Molpro software licence, you can contact Quantemol to receive a full package or contact Molpro separately)
  • SEP (alternative to HF and CI calculation model to enable high precision in calculation of the resonances i.e. providing a better estimation of dissociative attachment)
  • Dynamic clean ( calculation memory footprint optimisation)
  • Arrhenius parameters useful for plasma modelling input
  • SCOP improvement: improved calculation of charged densities and better calculation of rotationally resolved total cross sections and differential cross sections at high energies
  • SCATCI revised in R-Matix: electron configurations calculation optimised allowing for  larger molecule calculations

[expand title=”June 2015, Release 4.9.1″]

  • Geometry calculation bug fix
  • Molecular orbitals calculations optimised in R-matrix
  • Improvements to Molpro integration

[/expand]

 

[expand title=”May, 2015, Release 4.9″]

  • Bug fix so custom basis sets can be used with MolPro Orbitals
  • Bug fix to improve photoionisation calculations in with certain point groups
  • Bug fix to improve Static Exchange Hartree Fock calculations
  • Improvement to options to include excited states in calculation. Improvements makes inclusion of excited states for all symmetries more efficient and balanced
  • Addition of option to receive push notifications of calculations status to mobile phones and tablets
  • Option added to automatically delete all fort files created by a calculation to reduce memory footprint of calculation
  • Output to terminal created by calculation tidied up and output added to ease debugging of specific calculations. Automated naming of calculations tidied to improve clarity
