Since some entries for several command blocks in the batch file are identical, they are described in advance in this chapter.
Identification numbers
The data (input data and results) are specified using identification numbers (see 
Appendix) and, if necessary, the time step (for transient data).
Knowing the identification number is not required in the processing of the user interface. If the batch file, however, is created or edited with an editor, the ID number is relevant for the user.
The ID number -99 is used as a flag for intercalculated data. The transformation flag in other units and the time step are not be interpreted (batch command RECH).
Transformation of data into other units:
For the representation of some data (especially rates), the transformation into other units is possible in the plot generation.
Mass rates [m³ /? /TU] are converted to other units for the plot by specifying a transformation flag. The question mark within the unit means "per node or element". The transformation flags are defined as follows:
|
Transformation flag |
Unit in the plot |
|
10 |
[m³/?/a] |
|
11 |
[m³/?/m] |
|
12 |
[m³/?/d] |
|
13 |
[m³/?/h] |
|
14 |
[m³/?/min] |
|
15 |
[m³/?/s] |
|
20 |
[l/?/a] |
|
21 |
[l/?/d] |
|
22 |
[l/?/m] |
|
23 |
[l/?/h] |
|
24 |
[l/?/min] |
|
25 |
[l/?/s] |
Additionally, recharge rates (identification 111) can be transformed from [m³/element/TU] to:
In the user interface corresponding controls are available for specifying the unit.
Potential heads in 3D models at the free surface
It is difficult to represent equal-value lines/domains for potential heads in a horizontal section of a 3D model, because you'll never know the correct layer. Using the transformation flag 9 automatically creates the potential heads at the free surface, independent of the specified layer.
Coordinates instead of node numbers:
Some commands require a list of node or element numbers. This is the case for:
The input of numbers can be substituted by the input of coordinates:
First, you must add a negative sign to the number of input nodes. Then, the program reads coordinates (x, y) and if necessary a layer number (nr) instead of the node numbers (maximum 10 per line). Each line requires one node (x, y and possible nr), the single values separated by a blank or a tab. As a result, the program searches for the node or element centre which lies next to the coordinates. Finally, the program reports the selected node or element numbers and their distance to the coordinates.
