WinSteam 3.2
WinSteam provides accurate thermodynamic and transport properties of steam and water for Windows applications using the new IAPWS-IF97 formulations. WinSteam also allows you to select the IFC 1967 formulations for compatibility with older projects.
The steam property functions can be used directly from within applications including Microsoft Excel, Lotus 1-2-3 and MathSoft Mathcad. Add-ins attach the functions so that you can use them as if they were built in to the applications.
Programmers can call the WinSteam functions from Visual Basic or Visual C++. WinSteam also includes the stand-alone product DeskTop Steam, an advanced steam property calculator. If you do not need to access the steam functions from a spreadsheet, you may purchase DeskTop Steam alone.
What's New in Version 3.2
- Removed Help file link from Help Menu for Excel 2007 and later.
- Fixed some calculation convergence problems in critical region.
- Minor improvements in DeskTop Steam display.
WinSteam 3.2 is available as a free upgrade to licensed users of WinSteam 3.0 and 3.1
What's New in Version 3.1
- Added additional unit sets including metric units

Applications Supported
The WinSteam package includes various add-ins which link the functions to many popular 32-bit Windows applications. Add-ins are included for Microsoft Excel Versions for Office 95, Office 97, Office 2000 and Office XP; Lotus 1-2-3 97 and 1-2-3 Millennium and MathSoft Mathcad Plus Versions 6, 7 and 8.
No programming is required to use the WinSteam functions with any of these applications. Just follow a few simple steps to load the add-in, and from then on, the functions will be available every time you start the application. You use the functions just like any of the built-in functions. The functions can be used in any spreadsheet formula and any argument to the functions can be a number, a formula or a cell reference.
Programming Languages Supported
All of the steam property functions are contained in a Windows Dynamic Link Library (DLL). The WinSteam package includes a 32-bit version of the DLL, which supports applications designed for Windows 95, 98, NT, 2000 and XP. Function prototypes and LIB files are included in the package to support Microsoft C/C++ compilers. Declaration files are included to facilitate programming with Microsoft Visual Basic or Microsoft Access.
