A. Display Charts
Selecting 'Display Charts' from the pop-up menu launches five different charts:- Monitoring Wells plot
- Cross-section plot
- Cross-section diagram
- Mass Balance Bar Chart
- 3D surface plot
B. Display Subgrid Results
Click this option to overlay to the Map Display all of the subgrid (and parent grid) results for an unstructured grid model previously simulated in IGW-NET - either after having just finished running the model, or after loading the model into the Post-Analysis tool (see below).Unstructured grid models use lines, zones and wells to refine the grid in order to resolve more details in key areas of interest. The MODFLOW-6 solver must be used for unstructured grid modeling.
C. Save Model Image
This is a built-in screen capture tool that allows users to take a snapshot of the 'Whole page' (Map Display and button/interface environment) or just the 'Model Area' (whatever is being shown inside the model domain).The file is downloaded to the local machine as a .png file. For 'Model Area' downloads, the associated world file is available for download so that the .png file can be automatically georeferenced in a GIS program (e.g., QGIS).
D. Nodal Values
Selecting this option allows the user to click anywhere within the model domain to place a nodal value flag. Once a flag is placed, hover the cursor over it and click to view the model parameter values of the nearest node.To remove the flags and return the cursor to normal mode, click on the ViewResult button, then select NodalV Off.
E. Random Sampling
This tool allows users to sample model parameters (head, concentration, hydraulic conductivity, or aquifer elevation) of an existing model. The sampled data can be used in subsequent analysis (e.g., optimization problems or multi-parameter estimation exercises).F. View Run-time Msg
This tool is used to view the run-time log files and convergence histories of the most recently executed models/tasks in IGW-NET, e.g., a MODFLOW-based flow model log file, a Transition Probability (TP) run-time log file, etc.G. Post Analysis
This tool allows for analyzing the results of a previously executed flow model simulation (MAGNET or MODFLOW engine), TP simulation (3D aquifer material model), or multiple species transport simulation (MT3D-USGS model). For example, users can load a previously simulated flow model and:1) select any time-step and load the plan-view results (contours, vectors, etc.), cross-sections, 3D model visualization, model nodal values, and/or the current water balance;
2) display the model results and/or observed head and/or concentrations at monitoring wells locations within the model domain;
3) perform transient calibration (spatially-distributed at different times, and temporal trends); or
4) extract (download) the water table configuration at any time-step (even if it crosses computational layers)
