Equation Window

Ambiente de Trabajo

Equations Window

The Equations window operates very much like a word processor.

The equations that EES is to solve are entered in this window.

Editing commands, i.e., Cut, Copy, Paste, are located in the Edit menu and can be

applied in the usual manner.

Clicking the right mouse button on selected text in the Equations window will

bring up editing commands in a popup menu.

Equations Window

Additional information relevant to the Equations window follows.

1. Blank lines may be used to make the Equations window more legible.

2. Comments are enclosed in braces {comment} or in quote marks "another comment" and may span

multiple lines.

3. Equations are normally entered one per line, terminated by pressing the Return or Enter keys.

4. Equations may be entered in any order.

5. The order of mathematical operators used in the equations conform to the rules used in FORTRAN,

Basic, C or Pascal.

For example, the equation X = 3 + 4 * 5 could have been entered as (X – 3) / 4 = 5

Equations Window

Additional information relevant to the Equations window follows.

6. Upper and lower case letters are not distinguished.

7. Variable names must start with a letter and consist of any keyboard characters except (‘|)*/+-^{ } ":;.

The maximum variable length is 30 characters.

String variables hold character information and are identified with a $ as the last character in their

names, as in BASIC.

Array variables are identified with square braces around the array index or indices, e.g., X[5,3].

As a general rule, variables should not be given names that correspond to those of built-in functions

(e.g., pi, sin, enthalpy). 12

Ambiente de Trabajo

Formatted Equations Window

The Formatted Equations window displays

the equations entered in the Equations

window in n easy-to-read mathematical

format as shown in the sample windows

below.

Ambiente de Trabajo

Solution Window

The Solution window will automatically appear in front of all other windows after the calculations,

initiated with the Solve or Min/Max commands in the Calculate menu, are completed.

The values and units of all variables appearing in the Equations window will be shown in alphabetical

order using as many columns as can be fit across the window.

Ambiente de Trabajo

Arrays Window

EES allows the use of array variables. EES array variables have the array index in square brackets, e.g.,

X[5] and Y[6,2].

The values of all variables including array variables are normally displayed in the Solution window after

calculations are completed.

17

Ambiente de Trabajo

Residuals Window

The Residuals window indicates the equation blocking and calculation order used by EES, and the status

of the unit checking, in addition to the relative and absolute residual values.

The absolute residual of an equation is the difference between the values on the left and right hand

sides of the equation.

The relative residual is the magnitude of the absolute residual divided by the value of left side of the

equation

Parametric Table Window

A Parametric table operates somewhat like a spreadsheet. Numerical values can be entered into any of

the cells.

Ambiente de Trabajo

Diagram Window

The Diagram window serves several functions.

First, it provides a place to display a graphics and text relating to the problem that is being solved.

For example, a schematic diagram of a system identifying state point locations can be displayed in

the Diagram window to help interpret the equations in the Equations window.

Second, the Diagram window can be used for to provide convenient input and output of information and

for report generation.
