Figure 8.2.4: The
Piecewise-Polynomial Profile Panel
Specify the number of
Ranges. For the example of Equation
8.2-5, two ranges of temperatures are defined:
You may define up to three ranges. The ranges must be supplied in the order of increasing value of temperature. The solver will
not sort them for you.
For the first range (
Range = 1), specify the
Maximum temperatures, and the number of
Coefficients. (Up to eight coefficients are available.) The number of coefficients defines the order of the polynomial. The default of
1 defines a polynomial of order 0. The property will be constant and equal to the single coefficient
. An input of
2 defines a polynomial of order 1. The property will vary linearly with temperature and so on.
Define the coefficients. Coefficients
3,... correspond to
,... in Equation
8.2-3. The panel in Figure
8.2.4 shows the inputs for the first range of Equation
Increase the value of
Range and enter the
Maximum temperatures, number of
Coefficients, and the
,...) for the next range. Repeat if there is a third range.
