SET_SCALED_VARIABLE

This command is similar to SET_OPTIMIZING_VARIABLE in that it specifies start values for optimizing variables. The difference being it is functional for only one optimizing variable at one time. It also prescribes a minimum and maximum value for the variable. During the optimization runs, the variable value is limited within this min-max range.

Such a variable may have a value of zero or another start value, or may be fixed by SET_FIX_VARIABLE prior to the previous optimization run. For a good reference prior to using this command, a list of all variables (which are used to define various parameters for phases in the optimizing system, as entered in the *SETUP.TCM file or interactively entered in the GIBBS module) is obtained by using LIST_ALL_VARIABLES.

Syntax	set_scaled_variable
Prompts	Variable number: <Variable number(s)> Specify the number for an optimizing variable to be set. Any non-zero parameter is allowed to be optimized, and a parameter with a current value equal to zero must be specified explicitly here in order to be optimized.
	Start value /xxxx.xxxxx/: <A guess value> Specify a start guess of the optimum value. The current numerical value for the selected variable is shown as default. This guess is critical as the initial guess of all parameters must make it possible to calculate the selected equilibria.
	Min value /xxxx.xxxxx/: <A guess value> Specify a minimum guess of the optimum value. It should be smaller than, at least equal to, the current start value for the selected variable.
	Max value /xxxx.xxxxx/: <A guess value> Specify a maximum guess of the optimum value. It should be larger than, at least equal to, the current start value for the selected variable.
