-layer <ints:list of numbers> <str:name> [t <int:mult>]  [<ints:list of numbers> <str:name> [t <int:mult>]]

-layer t <int:mult> <ints:list of numbers> <str:name> [<ints:list of numbers> <str:name>]



Identifies specific layers or groups of layers over which a sum of a variable will be taken. A layer refers to nodes with the same layer number as defined in the HYDRUS graphical user interface.


The type of sum depends on the variable -  see REACTIVE_TRANSPORT_OUTPUT for variables defined with SELECTED_OUTPUT and -integralsum for variables defined with USER_PUNCH.




list of numbers

ints: List of material numbers to be grouped - more than one layer can be grouped within a single output file.

name

string: Name of the layer or group of layers. The name will be used in the name of the output file (layer_chem_name.out) and in the legend of the generated plots.

t

Indicator that next input is the integer mult.

mult

int: Integer indicating the regular time intervals at which the sum has to be executed. The input is given as a multiplier of the Time Interval for regular print times for time series as defined in the Print Information dialogue window of the graphical user interface. 



Example


In first option, different groups can be defined each with a different print interval. In the second option, all groups will have the same print interval.


Option 1


-layer 1-2 "Top" t 10 5 "Contamination" t 1


Two groups are defined. The first group named Top contains the nodes with a layer number 1 and 2 and will be printed at regular print intervals with a frequency 10 times less that the print interval defined in the Print Information dialogue window of the graphical user interface. The second group named Contamination contains the nodes with a layer number 5 and will be printed at each regular print interval as defined in the Print Information dialogue window of the graphical user interface.


Option 2


-layer t 1 1 "Ap"


The first layer (i.e. the nodes with the same layer number) is integrated at each regular print interval as defined in the Print Information dialogue window of the graphical user interface.
