Model grid mode

To run the AMWELLS model, use the dialog window "Run analytical model on the grid" that is launched from the Toolbar menu ( ).

 

 

 

After running the AMWELLS model (button "Run"), and while this dialog window is open, AMWELLS is operating in the Model grid mode.

In the Model grid mode you can:

·Calculate and display piezometric head and drawdown within a selected model cell at selected time;

·Plot hydrographs (piezometric head or drawdown versus time graphs) for any model cell;

·Plot hydraulic head or drawdown profile in the X-direction, the Y-direction or along the selected model cells;

·Determine the minimum or the maximum drawdown for the test duration or for the selected time interval;

·Specify ranges of displayed piezometric head or drawdown values that are displayed by different colors. Specify color classes options;

·See piezometric head variations as a 2-D and 3-D animation.

 

In the Model grid mode, drawdown is calculated in the cell centers that are usually not in the same locations as observation wells. This may result in calculated drawdowns being lower than that observed. Use button "Correction" to set up observation wells in the cell centers (see below).

The Model grid mode can operate while the Observation point mode is also active. In this case, AMWELLS gives priority to the Observation point mode.

 

 

 

 

Tab "Simulated result"


Shows results of AMWELLS in the Model grid mode in a table


Frame "Parameter"

Allows a choice between "Piezometric head" and "Drawdown" options

Frame "Time"

Selects prediction time

       List "Time units"

Specifies time units for the time value in the field "Time" (days, hours, minutes or seconds)

       Field "Number"

Information field that shows a number of a selected time step. A time step can be selected in the frame "Time"

Tab "Model grid"


Designs a uniform model grid based on entered number of model cells in the X-direction and the Y-direction


List "Aquifer for calculation"

Selection of an aquifer for the multilayer conceptual schemes

Frame "Pumping wells"

These fields are for information only. They indicate well coordinates and well  positions relative to the cell centers

Frame "Observation wells"

       Buttons "Correction"

Moves pumping or observation wells in the cell centers and saves new well coordinates. After applying these corrections, AMWELLS simulation in the Model grid mode has to be re-run

Option "Pumping well drawdown in the cell center"

Calculation of drawdown in a model cell accounts for positions of pumping wells. If this option is checked, the drawdown in the cell center will be equal to the drawdown in a pumping well within the same block

Button "Run"


Launches AMWELLS simulation in the Model grid mode

Button "Load"


Load simulated results for display

Button "Mesh"


Apply simulation results on the mesh in the graphical interface window

Button "Close"


Exits the Model grid mode
