Turbomole 6.6 released
« on: July 02, 2014, 09:09:10 pm »
Dear Turbomole users,

Turbomole version 6.6 and TmoleX 4.0 have been released.

Release Notes of Turbomole 6.6

  • New features:

    • RI-RPA gradients
    • Two-component TD-DFT for spin-orbit effects (escf) 
    • Solvation effects on excited states ADC(2) with COSMO (ricc2)
    • Reaction path optimization (new module: woelfling)
            The optimization starts with a linear synchronous transit (LST)
            followed by a chain-of-states method that optimizes reaction
            paths under the sole constraint of equally spaced structures.
            In contrast to Nudged Elastic Band or Growing String Method, it
            requires no spring forces, interpolation algorithms, or other
            heuristics to control structure distribution. [1]
    • M06 and M06-2X functionals (ridft, rdgrad, dscf, grad, aoforce, escf)
            The XCFun library (https://repo.ctcc.no/projects/xcfun/wiki)
            is now used for the evaluation of the aforementioned functionals.
    • VV10 like density based dispersion correction (ridft, rdgrad) [2]
    • Many body perturbation theory in the GW approximation (escf)
    • First order electron vibration coupling (new module: evib)
    • Two-component RI-RPA energies (rirpa)
    • CCSD(T) energy with interference-corrected MP2-F12 (ricc2)
  • Efficiency:
    • MP2/COSMO is included in ricc2. The rimp2 module is removed
          since all functionalities are now available in ricc2
    • community edition of IBM Platform MPI is included in the Turbomole distribution, for details see:
      IBM Platform MPI
      Turbomole users can run parallel calculations 'out-of-the-box' without the need to install MPI itself.
  • Usability:
    • New def2 basis sets for the Lanthanides [3]
    • New scripts and tools:
      • scanprep. Prepares a scan along frozen internal coordinates
      • log2rog. Calculate the radius of gyration from MD log files
      • past. Turns coord in principal axis system and prints rotational constants
    • TmoleX 4.0
      • A new look and feel and some code reorganisation
      • The builder is improved to more chemical intuition 
      • New option in Transition State Search: Reaction Path Sampling
      • First version of an online update possibility
