Run option 8

Run option 9

Run option 10

Run option 1

The choice multi run (run option 1) enables the performance of multiple simulation runs one after another with changing of the control configuration and with diverse input files (see example). After choosing the run option in the simulation control file (recommended extension *.sim) the number of simulations has to be declared additionally.

According to the number of simulations the complete records of the input files, including the location title and inventory number, are being declared. This means that the first run is being defined by the information up to line 52, and the definition of the next run starts at line 53 whereas all input files have to be declared once again. All control flags still apply further on, unless they are not overwritten explicitly.

Valid is always only the most recently generated constellation!

This option can be used for simulations at diverse locations as well as for a sensitivity analysis. In this last case (for consistent location) the data with the species parameters or the control flags are being changed.

For each simulation run the selected set of output data is created, that is generated from the run. The output files are indicated by the location name (site_name) and a numeration after the appendix out, res or ini. (see: Description of the output-files)

Run option 4

Similar to run option 8 the run option 4 enables the execution of several simulation runs with the same model control configuration. The structure of the simulation control file is the same up to line 43. Names of data files with special structure follow after the site_name (see table for run option 8). Unlike to run option 8 refers line 49 not to a file with the complete description of all soil data but only to a path of a directory which contains single files with soil data of each site. The names of this files mut have the structure wbuekxxx.sop with xxx is the identification of the soil profile.

The use of this option is not recommended.

Run option 7

Similar to run option 8 the run option 7 enables the execution of several simulation runs with the same model control configuration (see example). The structure of the simulation control file is the same up to line 43. The name of a data file with special structure follows after the site_name.
This site control file (recommended extension *.con) arranges the site depending files for each simulation run and the sequence of their simulations.
The following table lists the description of the control file from line 41 in case of flag_multi = 7..
