LIBPF 0.9 was released on 2010/06/02, 20 months and about 650 changes after release 0.8 (2008/09/22).

Apart from the usual extensive testing and optimization and bug-fixing the key improvements are:

• Calculation kernel:

  • Unit operation modeling: support for Proton-SOFC fuel cells;

  • Physical properties: major refactoring of phase- and stream-related classes, handling of root extrapolation (pseudoproperties) in cubic equations of state, PC-SAFT equation of state, prototype GERG-2004 and IAPWS-95 equations of state;

  • Systems: Classic OPC interface revamp, OPC Unified Architecture prototype interface, online software activation;

• User interface:

  • Internationalization: the User Interface is now available seven additional languages, for a total of twelve languages: Modern Standard Arabic, simplified Chinese, English, French, German, Hebrew, Italian, Japanese, Korean, Portuguese, Russian and Spanish;

  • Usability: added a Save As command.

In the following you can find the complete list of detailed changes from version 0.8 to version 0.9 for the calculation kernel and for the user interface.
