Engineering Equation Solver (EES)
Engineering Equation Solver (EES) is a commercial software package used for the solution of systems of simultaneous non-linear equations.
It provides many useful specialized 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.
EES stores thermodynamic properties, which eliminates iterative problem solving by hand through the use of code that calls properties at the specified thermodynamic properties. EES performs iterative solving, eliminating the tedious and time-consuming task of acquiring thermodynamic properties with its built-in functions.
