WinSim's Link2WinSim Process Simulation Solution

  • Component Physical Properties
  • Thermodynamics
  • Flash Calculations
  • Any Stream or Unit Model Calculations and Results
  • Used for building Digital Twins for over 30 years

What is Link2WinSim?
Link2WinSim allows anyone to embed the powerful capabilities of one of the most advanced process simulation companies in the world in their proprietary software.  Link2WinSim can help you enhance the capabilities of your proprietary software package or quickly enable the decision making of your field personnel.

What are typical applications for Link2WinSim?
Examples of typical applications include upgrading Original Equipment Manufacturer’s (OEM) sizing and rating software packages with physical properties and thermo options.  Automating calculations for non-engineering or field sales personnel with a MS Excel interface is another typical application.  If you have a potential application you would like to discuss, please contact us to learn more.

How can you Link2WinSim?
You can access Link2WinSim by using Microsoft Excel’s Visual Basic (VB) interface. VB and Visual C++ are the programming languages most commonly used to access Link2WinSim, but you can also use any software package that can call a Dynamic Link Library (DLL).

What is included in Link2WinSim?

Component Physical Properties

Over 1,200 pure components included.  Some of the properties included are:  Cp, Cv, Enthalpy, Entropy, Bubble Pt, Dew Pt, Compressibility, etc.

Component Physical Properties


Over 60 thermodynamic equations of state are available.  You can Link2WinSim Thermo for K Values, Enthalpy, Viscosity, Thermal Conductivity, and Surface Tension.   Bubble and Dew Points for mixtures and hydrate predictions are easily determined.  Phase envelopes and maps are easy to generate.

Here are the different thermodynamic methods currently available:
