EES will be used throughout the course as an aid for solving equations, plotting trends, etc. Students should become familiar with either EES or some similar mathematical equation solving program (Mathcad, Matlab, etc.).

EES is installed on the MNE PCStudio computers in Reber Building.
To get an account on these computers, fill out a form outside of room 224 Reber.

Your own personal copy of EES can be downloaded for free from Penn State's Angel website .

Note: Do not attempt to use the EES installation that comes with the textbook DVD - it does not work on newer computer operating systems. Instead, download EES from Angel.

Useful_tips_for_copying_EES_to_Word_and_Excel.pdf - This is a pdf file with instructions on how to copy table data and plots from EES into Excel or Word.

Here are some EES example files that you may download. To download and use:

1. Click on the desired file.
2. Depending on your browser, whether from a Windows or a linux machine, and how it is configured, it will either launch EES or prompt you as to whether you wish to open the file or save it.
3. If EES is loaded on your machine, choose the option to open the file. (You may have to browse to find the correct application.)
4. If EES is not loaded on your machine, choose the option to save the file.
5. Right-clicking on the file name works best on some browsers.

• Sample_simple_set_of_simultaneous_equations.EES - A simple application of EES to solve a set of three simultaneous equations.
  See also Sample_simple_set_of_simultaneous_equations.pdf - images of the EES windows for this example problem.
• MoodyChart_solver_example.EES - A simple application of EES to solve the Colebrook equation for friction factor f as a function of Reynolds number and nondimensional roughness coefficient. It works for laminar flow as well.
