Question
I would like to assign a specific value in elements with a certain condition (e.g. depth below 100 mm) in a dfsu file. Is it possible?
Answer
This is possible! You need to use Data Manager which can be found in MIKE+ 2D Overland Editors -see Fig.1
Fig. 1 - Data Manager Tool accessible from 2D Overland
When examining differences in maps, it is possible to eliminate all zero-values - or all values greater than a set threshold - in order to focus on the remaining data, assuming that we have a difference map where all zero-values are to be replaced by a delete value, e.g. 1.e-35.
The procedure is as follows:
1. Load the dfsu file into the Data Manager.
2. Select the item you wish to modify.
3. Start the Calculator.
4. In expression, type:
if(CurrItem<>0,CurrItem,1*10^(-35))
or
if(CurrItem!=0,CurrItem,1*10^(-35))
Note: CurrItem is not valid in the <else_expression>
5. We need to specify whether we want to modify all time steps, or just the current one.
6. Press Calculate and Click “Save” to save the file
