It is possible to execute the inverse calibration directly in the command line without using the dialog box, if a batch-file *. bsi exists in the directory. For this you have to change to the directory in which the calculation is to be executed. The input of sitra and confirming with the Enter key starts the calculation. The default file name is sitra.bsi. This file is searched in the directory.

To use another batch file, type sitra file name (the extension ".bsi" is automatically attached). Batch files can be created, viewed and modified with the help of any text editor

 

 

Example of a batch file sitra.bsi (steady state calculation):

 

out.s # Output file

1 # detailed protocol (1-yes/0-no)

1 0 # Equation solver P/U (1-iterative, 0-direct)

1 0 # Calculation of control lines (1-yes, 0-no), IMITTEL

0 0 # Peclet numbers, hydr. cond. from EICHEN (1-yes, 0-no)

STROEMUNG+INVERS inv.biv# inverse modelling without transport

1 # satur./unsat. computation (1-yes,0-no)

0 0 0 # equal conc., density-related calc., p or h (1-yes/0-no)

5 0.5 # Number of iteration steps, factor of attenuation

0 0 # Flow/transport steady st./0 trans./1 trans.+conf./unconf./2

0 0 # Initial values POTE/KONZ from ASAT(3) null(2) EICH/AKON(1) =0(0)

 

 

Example of a batch file inv.biv (inverse calculation), called from the steady state calculation:

 

out.inv # output file for inverse modelling record

invers.obs # observation data file

invers.csv # parameter file

1 # optimization with Levenberg-Marquard / 1: Quasi-Newton

10 # maximum number of iterations

KWER 1 0 # interpolation flags(if necessary) of KWER parameters / parameter d for distance weighting

SPEI 10 3 # interpolation (if necessary) of KSPE/parameter d for distance weighting

output = SENS;KOVAR

 

Meaning of the value of the interpolation flag:

0: Kriging

1: Gaussian

10: distance weighting – Sampson

11: distance weighting 1/d

12: distance weighting 1/d^2

13: distance weighting 1/d^4
