Step 6: Produce Output<br />
In addition to the water budget, PMWIN provides various possibilities for checking simulation<br />
results and creating graphical outputs. Pathlines and velocity vectors can be displayed by<br />
PMPATH. Using the Results Extractor, simulation results <strong>of</strong> any layer and time step can be<br />
read from the unformatted (binary) result files and saved in ASCII Matrix files. An ASCII<br />
Matrix file contains a value for each model cell in a layer. PMWIN can load ASCII matrix files<br />
into a model grid. The format <strong>of</strong> the ASCII Matrix file is described in Appendix 2. In the<br />
following, we will carry out the steps:<br />
1. Use the Results Extractor to read and save the calculated hydraulic heads.<br />
2. Generate a contour map based on the calculated hydraulic heads for the first layer.<br />
3. Use PMPATH to compute pathlines as well as the capture zone <strong>of</strong> the pumping well.<br />
