< Previous10 Figure 1-2: Hydrosimulatics Sign Up Form. Figure 1-3: Options for describing user job title/type and affiliation. The Guest Password can be used to allow others MAGNET users to load and view model results associated with the ‘Master’ user account, although guests can not edit/refine the model (e.g., they cannot add conceptual features, change inputs, etc. However, users can publish their models for other users to view and build upon (see section 7.2). 11 Finally, users may add additional information (optional) and choose if they would like to receive, via email, i) notifications about product updates from Hydrosimulatics; and ii) comments about models published by the user (see Section 7.2). The default setting is to receive notifications/comments via email. After completing all required fields, the user must read and agree to the conditions of Terms & Privacy, which can be accessed by clicking on the blue link at the bottom of the User Sign up Form. Click ‘Sign Up’ to complete the account creation. At any time, users can update their profile by accessing Account Login/Sign-up Interface and logging in using the username and password provided during account creation. In the case that the user has forgotten their user name and/or password, click ‘Forgot Password’ hyperlink (with grey font that turns red when hovering the cursor over it) in the Account login/sign-up interface (see Figure 1-1). A series of prompts will guide the user through recovery of their user name and/or password. A valid email addressed linked to the username is required. When logging into an existing account, the Hydrosimulatics Account Edit Form will appear (see Figure 1-4), which includes the same fields for editing that were included in the Hydrosimulatics Sign Up Form (Figure 1-2), but also additional features related to user accounts. In the bottom-left, information related to the Account Type (Free vs. Premium – see next section), the date the account was created, and the starting and end dates for premium subscriptions1. Users may also directly view messages sent to their account emails and view recent activity by using the hovering over and clicking the ‘View Message’ or ‘View Activity Report’ hyperlinks just above the Account Type information (seen Figure 1-5). 1 These will be the same as the ‘Created Date:’ for free users. 12 Figure 1-4: Hydrosimulatics Account Edit Form. Figure 1-5: View Message Box If the ‘View Activity Report’ option is selected, the user must specify a date (year, month, day) from which to extract an activity report, then click ‘Apply’. The report file will be outputted to the text box just below (see Figure 1-6). 13 Figure 1-6: Activity Report interface. If the ‘Click Available Download List’ option is selected, four clickable icons will appear (see Figure 1-7). • Clicking ‘IGW2D’ allows users to download/run the free-to-use IGW2D.exe application file on the local desktop. • Clicking ‘Latest Plane View Image (PRJ)’ downloads/opens a *.bmp image file of the latest model results (plan view display). • Clicking ‘Latest Model Results Files (txt)’ downloads/opens a MAGNET conceptual model file (i.e., the model domain and all of the conceptual features and parametrization options) that can be used for simulation/analysis/refinement at a later time). Also see Section 7.1. • Clicking ‘Latest Model Result Files (Binary)’ downloads a *.bin binary file containing model results from the last time-step (or steady-state results), specifically, the 2D or 3D head distribution and solute concentration distributions (if applicable).

Finally, at any time while using MAGNET, the user may log out from their account by selecting the ‘Logout’ button in the utilities menu. 1.4 MAGNET Premium Description coming soon. 14 15 Chapter 2 MAGNET MODELING ENVIRONMENT The MAGNET Modeling Environment shown in Figure 2-1 is divided into 7 parts (A through G) to facilitate its functionality and explanation of items/buttons/zones/etc. The subsequent sections explain each of these 7 parts of the Modeling Environment. 16 Figure 2-1: MAGNET Modeling Environment upon login. 2.1 Maps Display and Working Area The Maps Display and Working Area (MDWA) occupies a majority of the MAGNET Modeling Environment. THE MDWA is the region where conceptual modeling is performed and subsequent solutions are obtained (examples are shown throughout this manual). The MDWA is enabled with Google Maps (or, alternatively, the user may choose to use Microsoft Bing – this is detailed in the next version of the MAGNET Manual). The default view upon login is a map projection of the entire globe. 17 The user may navigate to different locations within the MDWA using the Navigation tools (see Section 2.3) or by click-dragging within the display. A double-click on the left mouse (LM) button anywhere will increase the zoom level (i.e., “zoom in”), and a double-click of the right mouse (RM) button decreases the zoom level (zoom out). Display will increase the zoom level (i.e., “zoom in”), and a double-right-click decreases the zoom level (“zoom out”). Additionally, the user can click and hold the Ctrl keyboard button while moving the scroll wheel on the mouse to zoom in or out. 2.2 Status Bar The status bar is located at the top of the MAGNET Modeling Environment. The status bar is used to display different messages related to the status of modeling jobs submitted to the MAGNET server (see examples in Table 2-1 below). Table 2-1: Examples of Status Bar messages displayed while modeling with MAGNET. 2.3 Map Display Tools Just below the Status Bar is a suite of standard map tools to help the user navigate to the area of interest and customize the background image. The user can use the text box to enter the coordinates (i.e., latitude and longitude) or name (formal or approximate) for the area of interest. The spatial extent of the display can be controlled with the ‘Zoom Level’ drop-down menu – increasing the zoom level increase the resolution (and decrease the spatial extent) and vice versa. 18 The Map Type drop-down menu allows the user to select from four background maps: TERRAIN (default setting); SATELLITE; ROADMAP; and HYBRID (satellite display with roads/names overlaid). Once changes in the text box and/or the drop-down menus have been made, apply them by clicking on the ‘Search’ button. An example is shown below. Figure 2-2: Using the Map Display Tools to customize the display. 2.4 Simulation Tools The Simulation Tools are used for executing a conceptual model created in the MDWA. Clicking the red ‘SIMULATE’ button initiates the process of the solving the groundwater equations for the domain created by the user. The ‘Forward’ and ‘Backward’ buttons are used to run a transient simulation forward or backward in time, respectively. The ‘Pause’ button pauses a transient simulation after solving the current time-step. The ‘Forward’, ‘Backward’, and ‘Pause’ buttons may also be used during particle tracking applications of a steady-state groundwater solution. More details related to model simulation are provided in Section 5.1 and elsewhere in this Manual. 2.5 Model Creation and Visualization Tools 19 The 2nd-tier of buttons along the left-side of the MAGNET Modeling Environment are used for creating and visualizing groundwater models. The red ‘DomainRect’ button allows the user to create a rectangular-shaped modeling domain within the MDWA. Similarly, ‘DomainZone’ allows the user to trace out a polygon of any shape as the model domain. More details are provided in Section 3.1. The ‘Well’ button allows users to add a well feature at any location within the model domain. These can be used “monitoring wells” to view and compare model predictions with observations, or they be used to simulate pumping/injection at a point. More details are provided in Section 4.3. The ‘CrossSection’ button is used to draw a cross-section visualization and analysis along polylines within the model domain. See more details in Section 5.4. The ‘Particle Tracking’ button expands to a sub-menu that includes tools for particle tracking applications useful for visualizing flow paths and groundwater source areas. More details are provided in Section 5.6. 2.6 Conceptual Features Tools The 3rd-tier of buttons along the left-side of the MAGNET Modeling Environment are used for creating conceptual features such aspolylines (e.g., streams, injection trenches, etc.) and zones (e.g., lakes, contaminant sources, polygons for water balance analysis, etc.). The ‘DrawPline’ button is used for creating a polyline feature within the model domain. The ‘AttrPlines’ is used to edit the attributes of any existing polyline feature. See Section 4.1 for complete details. The ‘DrawRect’ button creates a rectangular-shaped zone within the model domain. The ‘DrawZone’ button allows users to create zones of any shape. The ‘AttrZones’ is used to edit the attributes of any existing polyline feature. See Section 4.2 for complete details of implementation. The ‘SaveShape’ button is used to finalize the creation of a polyline or zones created in the model domain – this is a necessary function since the double-click mouse utility is reserved for changing the zoom level in the MDWA. 2.7 Utilities and Analysis Tools The 3rd-tier of buttons along the left-side of the MAGNET Modeling Environment are used for managing user background images, model files, and model input settings, as well as viewing model results and comparing outputs with observations (model calibration/evaluation). The ‘DefaultInput’ button provides access to the Default Model Parameters and Options menu (see Figure 2-3). This menu is used to: 1) assign grid and solver properties; 2) parameterize aquifer elevations, hydraulic conductivity and aquifer recharge; 3) apply boundary conditions from a “Parent Model”; 4) define transient simulation settings; and 5) customize particle tracking and model output display options. This menu will be thoroughly discussed in Chapter 3 and elsewhere in this manual. Next >
