If you have an old input file from a previous AIOMFAC run, this file can be used to perform new calculations for the same system. However, the system components cannot be further edited. The temperature and composition data of the input data points can be edited either directly in the input file or by using the input text area below (if you wish to change them).

The composition points entered in the text area below are appended at the end of the composition data in the uploaded file (ensure compatibility in terms of number of input columns – excluding the line no.).

Setting Temperature and Composition of Data Points

An example of correct input of data points is shown on the Hints & Examples page.

The first column is to set the temperature pertaining to a data point. (Click here to learn about the applicable temperature range.)
Followed by the mass or mole fraction value of the second component. The mass or mole fraction value of component no. 1 will be set automatically by AIOMFAC (the sum of all mass or mole fractions has to be equal to 1.0). If water is present in the system, it will be component no. 1.
The mole/mass fraction values of the remaining components follow in the order listed on the input-field header.
Table columns must be separated by a "space", "tab", or "comma + space".
Period (.) should be used as decimal point.
The web model allows input of up to 101 data points per model run.
One can also modifiy the composition and temperature of data points directly in the input file using a text editor.

T [K], mass or mole fractions of components: (excl. component 1; mass or mole fractions scale used depending on the setting in the input file)
