< Previous90 When the ‘Inside std’ option is selected, comparison points comparison points yielding residuals that are inside the CI and with a simulated head less than observed head are displayed as blue triangles in the MDWA. Conversely, comparison points y yielding residuals that are inside the CI and with a simulated head greater than observed head are displayed appear as red triangles (again, see Figure 6-12). Figure 6-12: Examples of residual mapping display options. 91 Chapter 7 UTILITIES & FILE FUNCTIONS This chapter describes tools/features used for saving or loading models, publishing and editing models and other file functions available in MAGNET. These capabilities are accessed in the Utilities sub-menu (Figure 7-1). Figure 7-1: Utilities sub-menu. 7.1 Saving and Loading Models In the current version of MAGNET, the conceptual model (i.e., the model domain and all of the conceptual features and parametrization options) can be saved for simulation/analysis/refinement at a later time. This can be done before submitting the model for simulation, after the simulation is completed (steady flow modeling) or when the simulation is paused (unsteady modeling). 92 To save a conceptual model, click the ‘SaveModel’ button along the left-side of the MAGNET modeling environment. This will launch the ‘Opening IGWMagnet Window) to save the MAGNET model file (ASCII/.txt format) to the local machine or directly open it with a ASCII/.txt editor. An example MAGNET model file is shown in Figure 7-2.20 To load a MAGNET model file, click the ‘LoadModel’ button along the left-side of the MAGNET modeling environment. This will open a sub-menu with three options: • Last Model on Server – which allows the latest conceptual model saved with MAGNET user account to be loaded; • Local Model File – which allows the user to browse to and load a MAGNET file saved on their local machine; • Help – this feature is not available in the current version of MAGNET. 7.2 Publishing & Editing MAGNET Network Models A powerful capability of MAGNET is to allow users to publish their model, results, and data on the MAGNET network to be viewed by other users. Specifically, users can publish/share: MAGNET model files (see previous section); image files of model results (e.g., head distributions, cross-sections, monitoring well plots, water balances); and/or animation files21 (e.g., transient head dynamics, particle tracking or contaminant transport). Users can decide whether to publish the conceptual model or just results (images or videos) and/or comments related to the model. If the conceptual model is published, other users can directly load it for editing on the MAGNET modeling web interface. 20 In future versions of MAGNET, user will be able to upload and share their models, data, and tools if desired. 21 Images and videos to be uploaded need to be prepared by the user, not the platform, either through screen capturing or using a commercial movie maker. Figure 7-2: Example MAGNET model file. 93 7.2.1 Publishing Models After creating and simulating a model, click the ‘Utilities’ button and then select ‘Publish This Model’ to launch the Model Publishing Options window (see Figure 7-3). This window allows uploading three image files related to model results and one video animation. Users should also provide a Model Name and a Model Description in the text boxes provided. To only share results, but not the conceptual model, check the box next to ‘Do not publish conceptual model file’. In fact, if users simply want to display the results of a model created with some other software/tool, they can simply draw a box presenting the modeling area, and proceed right to the Model Publishing Options window without submitting the model for simulation. The centroid location of the model (latitude and longitude, or Clat, Clong, respectively) will be used for further editing (see subsection 7.3.1). After adding all text/files, click the ‘Publish’ button to add the model and/or model results to the MAGNET Model Network. Or click the red ‘X’ to cancel the publication process. Figure 7-3: Example of publishing a model to the MAGNET network using the Model Publishing Options window. 94 7.2.1 MAGNET Modeling Network The MAGNET Model Network (Figure 7-4) can be accessed by clicking the ‘Model Network Website’ link in the Model Publishing Options window, or by navigating to: http://www.magnet4water.com/modelnetwork/ The different models created around the globe are shown as blue pin markers in the map display of the MAGNET Model Network. Comments about the platform/model network can be submitted to Hydrosimulatics using the interface in the bottom-left. Posted comments on are shown in the bottom-right. 95 Figure 7-4: MAGNET Model Network, available at www.magnet4water.com/modelnetwork/ . Zoom to and LM click on any pin to view more details about the model (date created, modeler/username, and latitude/longitude of the centroid of the model domain), and to access the model files/results (see Figure 7-8). Alternatively, users can use the search box to search for model name. Click the ‘Model File’ link to download the conceptual model file to a local drive so thatit can be at loaded at a later time for further development/analysis (see Section 7.1). Click the ‘Load Model to IGW Magnet’ to directly load the model to the MAGNET modeling environment (in a new web page/tab). 96 Click the ‘Model Image’ or ‘Model Video’ to open the model image or video file(s) in a new web page/tab. Figure 7-5: Selected model details in the MAGNET Model Network web interface. If the user clicks in the center part of model details window, the model results and comments page will launch (see Figure 7-6). This page allows for viewing the uploaded images and/or videos in greater detail. Visitors may also comment on and “rank” the model by visiting the comment interface in the bottom-left portion of the web-page. Comments will be sent directly to the model creator via email, and will be displayed in the right-hand-pane of the comment interface. 97 Figure 7-6: Model Results and Comments page. 7.3.1 Editing Your Published Models At any time, users can edit the settings of any of their published models by clicking the ‘Edit Published Models’ button in the Utilities submenu22. This opens the Edit Published Model Options window (Figure 7-7). 22 This requires that MAGNET users login/sign-up to the MAGNET Modeling Platform (see Section 1.3). 98 First, users to select from their list of published models from the drop-down menu. Then they can: • Replace the conceptual model file with the current model file (i.e., the model for the last job submitted) • Update whether or not the conceptual model file is published • Update/upload images or videos of the model • Add/update model name or a model description. Click ‘Update This Record’ to save the changes made, or click the red ‘X’ to cancel the editing process. Clicking the ‘Delete This Record’ button will remove the selected published model from the MAGET Model Network. Figure 7-7: Window for editing user published models. 7.3 Background Images 99 In some cases, it may be helpful/necessary to display an image layer in the MDWA (e.g., site drawings, GIS layers/maps of land or subsurface features, etc.). Use the ‘Utilities’ button along the left-side of the MAGNET modeling environment to access the sub-menu options for background images. Begin by using ‘Overlay myImage’ option to open the ‘Overlay an Image on Maps’ menu (see Figure 7-8). The text following “Note that:” provides details on the image requirements and the directions for specifying the image pathname if the web browser does not support local resource accessing. If the browser does support local resource accessing, click on the ‘Browse…’ button to navigate to the image location and open the image. Note that when using the ‘UpLoad’ option, the user must specify the overlay extent using the text boxes next to ‘Top Latitude’, ‘Right Longitude’, etc. Figure 7-8: 'Overlay an Image on Maps' menu. Similarly to hiding and re-displaying simulation results (see subsection 5.2.4), background images can be removed and re-displayed in the MDWA. Use the ‘Hide myImage’ option and the ‘Show myImage’ option from the Utilities sub-menu to hide and re-display the background images, respectively. To completely remove the background image from the MDWA, use the ‘Remove my Image’ option from the Utilities sub-menu. The ‘Down/UpLoad File button is disabled in the current version of MAGNET. 7.4 Geometry Lock/Unlock When a user draws a conceptual feature (polygon/zone, polyline, etc.), nodes (small circles are automatically displayed along the line segment/perimeter for “instant” editing of the geometry by click-dragging nodes into desired locations. However, in some cases displaying these nodes will obstruct a key conceptual feature or part of the background image, and the nodes may be unintentionally moved if the nodes are accidentally selected by the cursor.
