Engineering Equation Solver

Engineering Equation Solver (EES) is a commercial software package used for solution of systems of simultaneous non-linear equations. It provides many useful specialised functions and equations for the solution of thermodynamics and heat transfer problems, making it a useful and widely-used program for mechanical engineers working in these fields. The fact that EES stores thermodynamic properties can eliminate iterative problem solving by using code to call properties at the required state points, instead of iterating property look-ups until a solution is found.

The program is developed by F-Chart Software, a commercial spin-off of Prof Sanford A Klein from Department of Mechanical Engineering University of Wisconsin-Madison.

EES is included as attached software for a number of undergraduate thermodynamics, heat-transfer and fluid mechanics textbooks from McGraw-Hill.

It integrates closely with the dynamic system simulation package TRNSYS, by some of the same authors.
