If you are experiencing problems with EES that you believe to be a bug in the program, send a description of your problem about the EES program to Professor S.A. The CAE ENGINEERING LICENSING VPN will not work for downloading EES. The instructions for how to do this can also be found on Professor Klein's website.PLEASE NOTE THAT YOU MUST BE ON THE UW NETWORK, OR CoE NETWORK. Additional property data can be added.ĮES also allows user-written functions, procedures, modules, and tabular data. EES provides publication-quality plots, linear and non-linear regression, optimization, unit conversion and consistency checking, and uncertainty analyses.īuilt-in functions are provided for thermodynamic and transport properties of many substances, including steam, air, refrigerants, cryogenic fluids, JANAF table gases, hydrocarbons and psychrometrics. EES can also be used to solve initial value differential equations. EES can efficiently solve thousands of coupled non-linear algebraic equations. The basic function provided by EES is the solution of a set of algebraic equations. EES (pronounced 'ease') is an acronym for Engineering Equation Solver.
