Hello my friends,
DWSIM 1.5 Beta is now available for download. Here is the list of
changes since version 1.4:
- [NEW] Redesigned component database system
- [NEW] Added two new Property Packages: NRTL/Peng-Robinson and
UNIQUAC/Peng-Robinson
- [NEW] Added support for loading ChemSep(TM) databases
- [NEW] Added a tool to characterize petroleum fractions from ASTM/TBP
distillation curves
- [NEW] Added a tool to insert user-defined components
- [NEW] Added the ability to use multiple property packages in a
single simulation
- [NEW] Dockable help window with localized tips
- [NEW] New Unit Operations: Distillation Column, Absorption Column,
Refluxed Absorber and Reboiled Absorber
- [NEW] Rigorous Column solving methods: Bubble-Point, Sum-Rates and
Inside-Out
- [NEW] New utility for calculation of Petroleum Cold Flow Properties
- [CHG] Surface Tension is now correctly listed as a liquid phase
property
- [CHG] Redesigned splash and welcome screens
- [BUG] Fixed high-pressure vapor viscosity calculation
- [BUG] Fixed liquid viscosity calculation error when supercritical
components are present
- [BUG] Fixed flash calculation vapor fraction initialization error
(should avoid some impossible solutions)
- [BUG] Fixed culture-specific error related to Property Package
parameter storage
- [BUG] Fixed calculation of vapor phase thermal conductivity
- [BUG] Fixed a bug in internal calculation of heat capacity ratio
- [BUG] Fixed MRU filelist
The documentation was updated and I've added some samples to show you
some of the new features. More will come later.
Since this is a "beta" release, It would be good to get some feedback
from the users in order to fix the most critical bugs. One of them
would be the connections between streams and unit operations, which is
not working 100% yet, although it has been improving on every release.
In the next days I'll be adding some content to the new Wiki (http://
apps.sourceforge.net/mediawiki/dwsim/), so stay tuned for tips and
tricks, roadmaps and a tutorial on how to load a ChemSep database on
DWSIM.
