Different material properties can be assigned to individual model areas using zoning files. These are ASCII files with the following basic structure:

The first column contains the numbers of the zones that were assigned to the elements in the model file (attributes Z-KD, Z-AP). Parameters can be assigned to these zones according to their task (adsorption or decay and production:

 

• e.g. for adsorption according to Freundlich:

Zone number 1. Freundlich Isotherm 2. Freundlich Isotherm

1 0.001 0.001 #zone number CHI1 CHI2

 

 

• e.g. decay and production (step or triangular function):

Zone number Calc. method Max. slope lower limit upper limit

1 1 0 2 10 20 #Zone number, calc. method, PRODF0, PRODF1, U1PRODF, U2PRODF

 

with:

Calculation method = 1 ==> Application of the Step function

Calculation method = 2 ==> Application of the tent function

 

The individual parameters are separated by spaces or tabs; comments can be included after a ’#’.

The file with zoned parameters is created by entering a file name in the corresponding dialogue box, clicking the "Create file" button and then saving the batch file or starting the calculation. The defined values are saved in the "File for zoned parameters".

The relevant dialogue box only appears if the zoning attributes Z-AP (for decay and production) or Z-KD (for adsorption or heat) are present in the model file.
