1 BehavePlus fire modeling system, version 2.0 Operation Lesson 4 Calculation Self-Study In lessons 2 and 3 you learned how to set up a worksheet and to define input values. In this lesson you will do the calculations, producing tables and graphs. A range of values can be assigned to any input variable. Some, like fuel moisture, are continuous; any value within the valid range is meaningful. Others, like fuel model, are discrete; only specific values are meaningful. For example, dead fuel moisture can have a value of 4.6, but fuel model cannot. The form of the tables and graphs depends on how many input variables are assigned ranges (none, 1, or 2), and whether those variables are continuous or discrete. Remember to always keep a list of the input with every output table or graph that you produce. Single Value for Each Input Variable Select File > New. + next to the Example Worksheets folder to expand it. Double-click SlopeMap.bpw to open the slope-map worksheet. Enter values in the worksheet as shown below: Operation Lesson 4 Calculation April 2003 Page 1 of 21
