What's new in the 2014.01 version?
It is always a challenging question to answer when a technical software releases a new version since there always is a long list of what to improve around, all the way from
glimpse user-friendly aspects to improvements in computational algorithm.
But here is a list to briefly present the vital new features added:

  • A new gradient based optimization algorithm (Levenberg Marquardt) for EOS model regression
  • Domain Sensitivity Analysis Export to Pipesim (compositional model)
  • Mixture monotonicity check during mixture edition, regression and splitting
  • New plus fraction characterization correlations is now included: Hosseinifar-Jamshidi (2014)
  • A capability to compare the performance of any two mixtures on an experiment
  • Multiple related samples splitting (Gamma distribution method)
  • Regression on fluid composition by assuming constant feed weight percent and changing plus fraction molecular weight
  • Modified ternary phase envelope calculation algorithm
  • Quality lines to the phase envelope
  • CVD tests for oil samples
  • Plotting phase envelope gradient in Composition vs. Depth test
  • Duplicating a test in a mixture
  • Improvements in Export to Excel
  • Averaging multiple mixtures by mole fraction, mass fraction and arithmetic averaging
  • Automatic name selection for created pseudo-components after grouping
  • Sorting grouped fractions by their molecular weights after grouping
  • ِDuplicating test(s) from a mixture to other mixtures
  • A capability to compare critical tests before and after tuning, splitting and grouping
  • Modification in some of viscosity calculation algorithms
  • Using multiplier in table unit converter
In addition to the above list, there are some new case studies added to the software which can be used as instantaneous used guides. Like always, the PVTmaster Development Team came up with some interesting improvements in user interface and also a number of functionality bugs are now fixed.

We decided to simply replace the previous version with the new one, so from now on only the latest version will be available to download in the website and the older versions are kept in a private repository and not the website. We would be also very happy to have your feedback on how the new version meets your expectation.
