IMPORT

This command is for the ED-EXP module.

Transfer/import the value of one of the optimizing variables to a constant. Normally, it is directly used inside an experimental data (*.POP) file. It is the opposite of the EXPORT command.

In the DICTRA module, you work with a .DOP file instead of a .POP file.

The IMPORT command is useful if several experiments are done at the same activity of a component, but this activity is not known. The activity should then be optimized and all equilibria with the same activity should use the same value. In this case the variable must be set as an optimizing variable, and an initial guess of the activity should be given. During the optimization, the PARROT program tries to find the activity that gives the best fit.

If an approximate value of the activity is known, it can be supplied as an experiment.

Syntax

import

Prompt

Constant name: <Constant name>#<n>

The value of the V variable must be assigned a symbolic constant. The number (n) of the V variable must be given after the constant name, separated by hash character #.

The constant name is UPPER/lowercase sensitive, and it should normally be given in UPPER case.

 

Enter_constant acu=0.1

Import acu#2

This transfers the value of the optimizing variable 2 (i.e. V2) to the constant ACU.
