This screen lists all parameters that can be changed by the user.
For a normal deterministic simulation, you need to enter a nominal value for each parameter. For a probabilistic simulation, you need also to assign probability density functions to the uncertain parameters that you wish to include in the analysis.

Select a parameter in the list to edit its data. A short presentation of the parameter is displayed on the right hand side. Under, in the Data section, a table with the data for the parameter is displayed.
When you click a cell in the table an editor will appear under the table which can assist you in setting a value for the parameter.
1) - Click the button to display this header.
Below the table are four buttons:
Transpose the table (switch rows for columns). Only available for objects with one or more dimensions. | |
Hide default rows/columns. | |
Hide the non-default rows/columns. | |
Show (or hide) more headers. Some headers are originally hidden, such as headers for comments and statistics |
The editor appears when you click in a field in the table. When you click a field for a numeric value, an editor which can help you convert values from one unit to another. When you click a PDF the PDF editor appears. You can hide the editor by clicking the Toggle button.
The constants editing tool appears when a table cell is clicked that contains a number. It can be hidden by clicking the Toggle button, as shown in the screen shot below.
The editor contains two tools:
Keypad - Use the keypad with the mouse to enter a value or an operator without having to use the keyboard.
Unit conversion - This tool lets you convert a numerical value from one unit to another (compatible) unit.
Choose a probability density function from the Distribution functions drop-down list. Input fields will appear depending on the number of arguments required for the selected function.
The Upper trunc and Lower trunc fields are always available and can be used to truncate the function. Lower trunc is often used to avoid negative values for parameters.
See probability density functions for a list of all PDFs.
The PDF Editor has four tools, which are accessed through the buttons next to the Editor button.
The chart tool displays a graph of the current function. By using the buttons on the left hand side you can choose to plot
Delimiters and calculated values from the calculation tool are displayed in the graph using markers.
Displays statistics on the currently selected function.
Allows you to calculate values and percentiles for the current function. These values are marked in the graph of the Chart tool. Information
Describes the currently selected function and it’s parameters.
