Engineering Equation Solver

Engineering Equation Solver (EES)

Engineering Equation Solver (EES) numerical equation solver software used for complex system of coupled non-linear algebraic and differential equations, with built-in thermophysical and transport property functions for water, humid air, and many refrigerants.

What is Engineering Equation Solver?

Engineering Equation Solver (EES) is a numerical equation solver computer program used mainly for solving complex system of coupled non-linear algebraic and differential equations. It was developed originally by Sanford Klein and William Beckman at University of Wisconsin-Madison in 1992.

EES has extensive built-in thermophysical and transport property functions for water, humid air, and many common refrigerants. It also has the capability to call external dynamic link library (DLL) functions written in Fortran, C, Pascal, etc. This allows the user to augment the built-in functions with custom procedures.

Some of the key features of EES include:

• Equation solver for systems of coupled non-linear equations
• Handles complex variables
• Built-in property data for many substances including water, humid air and various refrigerants
• Parametric tables
• Array equations
• Integral and differential equation solving
• Uncertainty propagation and statistical analysis tools
• Optimization
• Dynamic link libraries for calling external functions
• Scripting language for automating tasks
• Add-on libraries for additional functionality (e.g. psychrometrics, steam tables, fuels combustion)

EES finds widespread use across many engineering disciplines including mechanical, aerospace, chemical, civil, electrical for analyzing thermodynamic systems, heat transfer, fluid flow, mass and energy balances, electronics, statistical analysis, optimization, uncertainty analysis among many other applications.
