EES Engineering Equation Solver is a software tool that solves systems of nonlinear equations using built-in functions and physical property data. It combines algebraic, differential, and integer equations with tables of data.
EES uses a proprietary algorithm to solve equations numerically. Unlike symbolic solvers, it doesn't find analytical solutions but provides numerical results. The software includes over 1,600 built-in functions for mathematical, thermodynamic, and economic calculations.
EES offers several key features:
Engineers use EES for various applications, including:
| Field | Example Application |
|---|---|
| Thermodynamics | Refrigeration cycle analysis |
| Fluid Mechanics | Pipe flow calculations |
| Electrical Engineering | Circuit analysis |
| Mechanical Engineering | Stress analysis |
Unlike general-purpose programming languages or other equation solvers, EES is specifically designed for engineering problems. It includes specialized functions for engineering units and physical properties, making it more efficient for engineering applications.
I've used EES to model a heat exchanger system, which required solving multiple coupled equations simultaneously. The software's ability to handle these complex interactions made the process much more efficient than using traditional methods.
F-Chart Software offers complete documentation and tutorials for EES. The software also includes a built-in help system with examples for common engineering problems.
According to the EES website, over 100,000 engineers worldwide use the software for teaching, research, and professional work. Its versatility makes it suitable for many engineering disciplines.
