EES - Engineering Equation Solver at UW 10.1

EES – Engineering Equation Solver at UW is the University of Wisconsin edition of EES, a numerical modeling environment developed by F-Chart Software. It solves large sets of coupled, nonlinear algebraic and differential equations and includes extensive thermophysical property data, unit-aware variables, and tools tailored for engineering analysis. Widely used in thermodynamics, heat transfer, fluid mechanics, and energy systems, EES helps students and researchers translate equations into reliable results quickly.

Key capabilities:

• Robust solvers for nonlinear systems and initial-value ODEs
• Built-in properties for pure fluids, mixtures, refrigerants, humid air, and steam (with psychrometrics and steam tables)
• Dimensioned variables with automatic unit consistency checking
• Parametric studies, design optimization, and uncertainty propagation
• Integrated plotting, tables, regression, and curve fitting
• Diagram and program windows for readable models and interactive schematics
• Import/export and automation features for repeatable workflows

At UW, EES supports coursework, labs, and research by providing a single, integrated environment for cycle analysis (Rankine, Brayton, and refrigeration), heat exchanger design, pipe flow and compressible flow calculations, and modeling of renewable and building energy systems.
