Engineering Equation Solver Professional: A Powerful Tool for Engineers




Engineering Equation Solver (EES) is a software program that can solve thousands of coupled non-linear algebraic and differential equations. EES can also perform linear and non-linear regression, optimization, unit conversion, uncertainty analysis, and more. EES is designed for engineers who need to solve complex problems in thermodynamics, heat transfer, fluid mechanics, and other engineering disciplines.

EES has a user-friendly interface that allows you to enter equations and variables in natural notation, similar to how you would write them on paper. You can also create graphical user interfaces with buttons, plots, tables, diagrams, and other elements to interact with your EES model. EES can generate high-quality plots and reports that can be exported to various formats, such as PDF, HTML, Excel, and Word.


EES comes in two versions: Commercial and Professional. The Commercial version is intended for general engineering applications, while the Professional version has additional features that are useful for advanced users and educators. Some of the features that are exclusive to the Professional version are:


  • The ability to create child diagram windows that can be linked to the main diagram window. This allows you to create complex applications with multiple screens and menus.



  • The ability to create hot areas on the diagram window that can trigger actions when clicked. For example, you can create a button that opens a plot window or a table window.



  • The ability to create check boxes and radio groups that can be used to control the values of variables or the visibility of elements on the diagram window.



  • The ability to create audio-visual items that can play sounds or videos on the diagram window.



  • The ability to save and load user inputs in a separate file. This allows you to create applications that can store user preferences or data.



  • The ability to use animation on the diagram window. You can create dynamic graphics that change with time or with the values of variables.



If you are interested in learning more about EES and its capabilities, you can download the EES manual or watch some YouTube tutorials. You can also download a webinar that provides instructions for accessing property information in EES, or read Chapter 1 of the Mastering EES book that provides a detailed introduction to EES.


If you are a student or a faculty member in the College of Engineering at the University of Wisconsin, you can download the Academic EES program for free and use it on your Windows-based personal computer. However, you need to be connected to the UW-Madison internet system to use the Academic EES program. If you are not connected, the program will stop after a few minutes and you will lose your work. You may be able to use EES off-campus by installing WiscVPN on your computer.


If you want to purchase the Commercial or Professional version of EES, you can visit the F-Chart website and place your order online. You can also contact F-Chart by email at info@fchart.com if you have any questions or comments about EES.


EES is a powerful tool that can help you solve engineering problems faster and easier. Whether you are a student, a teacher, or a professional engineer, you can benefit from using EES for your engineering projects. How to Use EES Professional for Solving Engineering Problems




In this section, we will show you how to use some of the features of EES Professional for solving engineering problems. We will use an example problem from thermodynamics as a case study. The problem is as follows:


A piston-cylinder device contains 0.1 kg of air at 300 K and 200 kPa. The air is heated at constant pressure until its temperature reaches 600 K. Determine the work and heat transfer for this process, and the final volume of the air.


To solve this problem using EES Professional, we need to follow these steps:


  • Create a new file and save it as "Thermo Example.ees".



  • Enter the given data and the unknowns in the Equations window. Use the SI units system and the EES variable naming conventions. For example, enter "m=0.1 [kg]" for the mass of the air, and "W=? [kJ]" for the work.



  • Enter the equations that relate the variables in the Equations window. Use the EES built-in functions and thermodynamic property data. For example, enter "h1=enthalpy(Air,T=T1,P=P1)" for the specific enthalpy of the air at state 1, and "W=m*(h2-h1)" for the work done by the air.



  • Solve the equations by clicking on the Solve button or pressing F2. EES will display the values of the unknowns in the Solution window. You can also view the values of other variables by using the Variable Info tool or by typing their names in the Command window.



  • Create a plot of the process on a P-V diagram by using the Plot window. To do this, click on the Plot button or press F9, and then select "New Plot". Choose "Pressure" as the x-axis variable and "Volume" as the y-axis variable. Click on "Add Curve" and select "Equation" as the curve type. Enter "T=600 [K]" as the equation for the curve, and choose a color and a line style for it. Click on "OK" to create the plot.



  • Create a table that shows the properties of the air at state 1 and state 2 by using the Table window. To do this, click on the Table button or press F10, and then select "New Table". Choose "Vertical" as the table orientation and "Fixed" as the table type. Click on "Add Column" and select "Variable List" as the column type. Enter "T,P,v,h,s" as the variable list for the column, and choose a format and a unit system for it. Click on "OK" to create the table.



  • Create a diagram that shows the piston-cylinder device and its dimensions by using the Diagram window. To do this, click on the Diagram button or press F11, and then select "New Diagram". Use the drawing tools to create a rectangle that represents the cylinder, a circle that represents the piston, and a line that represents the heat source. Use the text tool to add labels and values to the diagram elements. Use the dimension tool to add dimensions to the diagram elements.



After completing these steps, you should have a file that looks like this:
