3. Press the right mouse button once.
The Data Editor displays a dialog box.
4. In the dialog box, type new value(s) then click to transfer the new zone value(s) to
cells.
Note that PMWIN always uses cell data for computations, and if zone data are not transferred
to the grid cells, the original values in the cells are used.
< To modify a zone
1. You may shift a vertex of a zone by pointing the mouse cursor at the vertex node and
pressing down the left mouse button while moving the mouse.
2. If you have several zones, some zones can intersect or even cover other zones. If you move
the mouse cursor into a covered zone, the boundary of the zone will not be highlighted. In
this case, you can move the mouse cursor into that zone, hold down the Ctrl-key and press
the left mouse button once. The Data Editor will resort the order of the zones and the "lost"
zone will be recovered.
3.2.3 Specification of Data for Transient Simulations
If your model has more than one stress period, a Temporal Data dialog box appears after
clicking the leave editor button . This dialog box allows you to manage your model data for
transient simulations:
1. You can edit model data for a particular stress period by selecting a row of the table and
clicking the Edit Data button. After having specified the model data of a stress period, the
Data flag in the corresponding row is checked.
2. You may click on a Use flag to check or uncheck it. If the Use flag is checked, the data of
the corresponding stress period will be used for the flow simulation. If the Use flag is not
checked, the data of the previous stress period will be used. The Use flag of a stress period
is automatically deactivated if the corresponding model data are not available.
3. Use Copy Data, if you want to copy model data from one stress period to another.
Fig. 3.9 shows an example in which the data for the periods 1, 3, 4 are specified. The specified
data of the first period will be used throughout the first three periods. The data of the fourth
period will be used for the rest of the simulation. The data of the thrid period will not be used
because the Use flag is cleared.
