Switch to the Cell-by-cell input method. Polygon method Switch to the Zone input method. Polyline method Switch to the Polyline input method. Grid view Switch to the Grid View display mode. Map view Switch to the Map View display mode. Column View Switch to the column cross-sectional display mode.

Row View Switch to the row cross-sectional display mode. Duplication is on, when this button is depressed. Change period Manage model data for transient simulations. The Data Editor Cross-sectional View 2. Click the assign value button.

It is not necessary to click this button, if the button is already depressed. Move the grid cursor to the desired cell by using the arrow keys or by clicking the mouse on the cell. The value s of the current cell is are displayed in the status bar. Press the Enter key or press the right mouse button once.

The Data Editor shows a dialog box. In the dialog box, type new value s then click OK. Since groundwater model data are often very complex, PMWIN Pro provides several possibilities for checking or modifying cell-by-cell model data as listed below.

All model cells with the same value will appear in the same color. The color can be changed by repeated double-clicks. The Cell Information dialog box Fig. Open the Cell Information dialog box Fig. This allows you to display all cells that have a value located within the Search Range to be specified.

According to the user specified Value and the operation Options, you can easily modify the cell values. For example, if Add is used, the user-specified value will be added to the cell value. The Parameter drop-down box shows the available parameter type s. The user may select the parameter to which the subsequent Search and Modify operation will be applied.

Open a Search and Modify dialog box for more advanced data manipulation features. See Section 2. This input method is not allowed in the cross-sectional view. To activate this method, click on the button or the button to switch to Grid View or Map View, and then click on the button or choose Options Input 20 2 Modeling Environment Method Polygon. The use of this input method is straightforward. First, you draw a polygon and then assign parameter values to the polygon.

Finally, press the button to apply the parameter values to model cells that lie within the polygon. If polygon data is not applied to the model cells, the original values in the cells are used. I To draw a polygon 1. Click the assign value button and click the button. Click the mouse pointer on a desired position to anchor one end of a line. Move the mouse pointer to another position then press the left mouse button again. Repeat steps 3 and 4 until the polygon is closed or press the right mouse button to abort.

I To delete a polygon 1. Move the mouse pointer into a polygon. The boundary of the polygon will be highlighted. Press the Delete key. The value s of the polygon will be displayed in the status bar. Press the right mouse button once. The Data Editor displays a dialog box, which allows the user to assign parameter value s to the polygon. In the dialog box, type new parameter value s then click the button to apply the parameter value s to the model cells within the polygon.

The user may drag vertices of a polygon by pointing the mouse pointer at a vertex node and pressing down the left mouse button while moving the mouse. If there are several polygons, some polygons can intersect or even cover other polygons. If the mouse pointer is moved into a covered polygon, the boundary of the polygon will not be highlighted. In this case, simply move the mouse pointer into that polygon, hold down the Ctrl key and press the left mouse button once.

This input method is not allowed in the button or the butcross-sectional view. First, you draw a polyline along a drain, river, or stream, and then assign parameter values to vertices of the polyline. Properties needed for cells along traces of polylines are obtained using the parameter values of vertices.

I To draw a polyline 1. Repeat steps 3 and 4 until the desired polyline is drawn, click on the latest vertex again to complete the polyline or press the right mouse button to abort drawing. I To delete a polyline 1. Move the mouse pointer over a polyline. The polyline will be highlighted. Refer to the explanation of the River, Drain, General-head boundary, and Streamflow-routing packages for details about the required parameters of each package. I To assign value s to polylines 1.

Move the mouse pointer over a vertex and right-click. The Data Editor displays a dialog box, which allows the user to assign parameter value s to the vertex. In the dialog box, type new parameter value s. Once the parameter values are specified, the display color of the vertex is changed to indicate that its parameter values are specified.

I To modify a polyline 1. The user may drag vertices of a polyline by pointing the mouse pointer at a vertex node, pressing down the left mouse button, and moving the mouse. Clicking on this button opens the Temporal Data dialog box Fig. The following describes the use of the dialog box. The boxes in the Data Status column have three states: — : Model data has been specified and will be used for the simulation.

The model data from the previous stress period will be used for the simulation. Click on the Data boxes to toggle between and. 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 model data of the third period has been specified, but will not be used for the simulation since the Data Status is.

After having specified the model data of a stress period, the Data status changes to. A New Model dialog box allows the user to specify a filename on any available folder or drive for the new model. All file names valid under the MS Windows operating system with up to characters can be used. It is a good idea to save every model in a separate folder, where the model and its output data will be kept.

This will also allow the user to run several models simultaneously multitasking. The tabs are described below. Independent of the selected tab, the user can specify refinement factors for both column and row directions. In this way, one can load or create a model with a higher resolution for transport simulations. Refer to Section 6. Then click the Convert button. The sub-region is defined by the starting and ending columns and rows. PMWIN Pro automatically transfers the model parameters and the calculated heads from the regional model to the sub-model.

The boundary of the submodel will be set to constant head boundary for steady-state simulations or time-variant specified-head boundary for transient simulations. The settings of the dialog box are described below.
