Once MODFLOW has successfully completed, Choose YES to post-process the results

Specify what model results to analyze (include a check next to “CBC Files” to allow viewing of the mass balance)

Be wary that the proper path and file names appear here

You can get to this screen to import any previously created results via Plot>ImportResults

Click OK

Check the model is doing what you expect by reading through the output, by dragging t2.out into textpad
if so, check the mass balance (either in t2,out, or by Plot>MassBalance>ModelSummary, if it is not acceptable

Select Model->MODFLOW->SolverPackage

Decrease the tolerance, possibly increase the number of iterations if almost all were used last time

Repeat creation of MODFLOW files and execution until convergence with reasonable mass balance is concerned

 

HEAD CONTOURS WILL APPEAR

Select Plot>Contour>Parameters(plan) and adjust contours as desired

Mine look like this:



Toggle through the layers to see how heads change with depth

Plot velocity vectors on the map and cross-section by selecting
Plot->What to Display…
Check Vectors
Select Plot>VectorOptions to adjust the appearance of the vectors



Plot a color flood map by selecting
Plot->What to Display…
Check Color Flood




Take a closer look at the cross section view

Drag the bar that separates the cross section from the plan view down

Select Plot>Contours>Parameters(Section)

Consider the calculated Z range (in this case heads)

Set the contour controls at reasonable values

To obtain for row 1

To view along columns rather than rows Select XSect>Selection

Take a little time to change the rows and columns, and view other sections

Adjusting for column 1



Try viewing color floods and vectors

Adjust parameters controlling the contours and the size of vectors appropriately each time until you have a good "feel" for the flow system

My view along row 8 is

Explore GWV plotting feature:

To view the Mass Balance, Select Plot->Mass Balance->Model Summary

A table similar to the MODFLOW output summary appears

Click Graph to produce a bar chart of the mass balance

Flux rates are also displayed on the status bar based on cursor position

Switch to the BC mode

Switch to layer 1

Place the cursor over a constant head cell

The negative represents flow leaving the model

Place the cursor over a constant head cell

To view profiles of head, concentration, drawdown, or water flux plotted versus distance along a cross-section,

Select Plot-> Profile->Head

Double click on items such as axis labels to change to desired settings

Right click on the graph to print, export, or modify the chart.

Here is my profile for row 8
