| {{Current development}} | | HydroGeoSphere (HGS) is a three-dimensional control-volume finite element simulator created by [https://www.aquanty.com/ Aquanty]. HGS can be used to model the entire terrestrial portion of the hydrologic cycle. It uses a globally-implicit approach to simultaneously solve the 2D diffusive-wave equation for overland/surface water flow and the 3D form of Richards’ equation for variably saturated groundwater flow. GMS allows multiple HGS simulations to exist in a single GMS project. Users should note that while GMS uses the terms “points” and “cells” for UGrids, HGS uses the terms “nodes” and “elements” regarding this tool. |

| ===Working with Simulations===
| |
| A simulation can be created by right-clicking on a blank portion of the Project Explorer and choosing the ''New Simulation'' submenu. The ''New Simulation'' menu will have commands to create a new model simulation. Selecting a model will cause a simulation folder [[File:Simulation Folder Icon.svg|16 px]] for the chosen model to appear in the Project Explorer.
| |
| | |
| After a simulation [[File:Simulation Icon.svg|16 px]] has been created, components may be added to the simulation. Components are often created as map coverages, meshes, grids, or scatter sets. The individual map coverages, grids, or scatter sets can be linked to the simulation by clicking on the item in the Project Explorer and dragging it under the simulation item in the Project Explorer. Each simulation in the Project Explorer will show a list of all linked components [[File:Coverage Link.svg|16 px]]. This allows multiple simulations to make use of the same datasets.
| |
| | |
| Components can also be added to a simulation using the right-click ''Apply To'' submenus.
| |
| | |
| Once a simulation exists, future simulations are often similar to one already created. Often it is easier to make a copy of the simulation and make changes where appropriate. A simulation can be copied by right-clicking on the simulation and choosing '''Duplicate'''. All simulations for a model will be listed under the simulation [[File:Simulation Icon.svg|16 px]] for that model. Under the simulation data [[File:Simulation Data Icon.svg|16 px]] item all simulations for all models will be listed—SMS supports using more than one model for a project.
| |
| | |
| :'''''Note:''''' When naming simulations, apostrophes are not allowed in the simulation name. Using an apostrophe in any simulation name may cause an error.
| |
| | |
| The right-click menu for a simulation includes menu commands specific to each model.
| |
| | |
| === Simulation Menu Preferences ===
| |
| In addition to some general commands, which are described below, the user has control over a set of simulation right-click menu options. These options are accessed by pressing the '''Edit''' button in the [[SMS:Preferences#Project Explorer|''Project Explorer'']] tab of the [[SMS:Preferences|''SMS Preferences'']] dialog. This dialog is accessed in the ''Edit'' menu using the '''Preferences''' command.
| |
| <!--Update template-->
| |
| The options in this dialog allow hiding or showing menu commands for the simulation right-click menus. The dialog has the following options:
| |
| *''Simulation'' – This section is for turning on and off commands located in the simulation right-click menu for individual simulations. It includes the following commands: | |
| **Save Simulation
| |
| **Run Simulation
| |
| **Save Simulation and Run
| |
| **Save Project and Simulation
| |
| ** Save Project, Simulation and Run
| |
| *''Multiple Simulations for Model'' – This section is for turning on and off commands for the simulation data right-click menu that affects multiple simulations. This is accessed by right-clicking on the simulation folder [[File:Simulation Folder Icon.svg|16 px]] for each numerical model. It includes the following commands:
| |
| **Save Multiple Simulations
| |
| **Run Multiple Simulations
| |
| **Save Multiple Simulations and Run
| |
| **Save Project and Multiple Simulations
| |
| ** Save Project, Multiple Simulations and Run
| |
| :'''''Note:''''' Saving a project does not save files used by the numeric model for the simulation run. The simulation must be saved for these files to be exported from the project.
| |
| | |
| :'''''Note:''''' Some models do not support a Save and/or Run command. Menus selected in this dialog may not appear for those models. For example, if the '''Save Simulation and Run''' was the only menu item selected, but the model only supports the '''Save''' command, then the '''Save Simulation''' command would appear instead of the '''Save Simulation and Run''' command.
| |
| | |
| ===General Simulation Right-Click Menu Commands===
| |
| {{Anchor|Simulation Menu}}
| |
| Right-clicking on any simulation object [[File:Simulation Icon.svg|16 px]] in the Project Explorer will bring up a menu for that simulation. Some of the commands are specific for the simulation model type. The simulation right-click menu has the following commands that are used by all simulations.
| |
| * '''Rename''' – Allows changing the simulation name.
| |
| * '''Duplicate''' – Creates a copy of the selected simulation. All components linked to selected simulation will be linked to the duplicate simulation. Adding, or removing the components in the duplicate simulation will not change the original simulation.
| |
| * '''Delete''' – Removes the selected simulation. This command does not delete or modify components linked to the simulation.
| |
| * '''Properties''' – Brings up a ''Properties'' dialog that shows which model the simulation is using and what components have been applied.
| |
|
| |
|
| Right-clicking on the simulation folder [[File:Simulation Folder Icon.svg|16 px]] always includes the following commands: | | ===Creating a New HydroGeoSphere Simulation === |
| * '''New Simulation''' – This command will create a new simulation of the same model type as the simulation folder.
| | [[File:Hgs simulation.png|thumb|250 px|Example of a HydroGeoSphere simulation in the Project Explorer]] |
| * '''Simulation Run Queue''' – Opens the [[SMS:Simulations#Simulation_Run_Queue|''Simulation Run Queue'']] dialog.
| | To create a HydroGeoSphere simulation: |
| | # Right-click on an empty space in the Project Explorer, or right-click on "[[File:Project Icon.svg|16 px]] Project" in the Project Explorer, and select ''New Simulation'' | '''HydroGeoSphere'''. |
|
| |
|
| Additional commands appear in the simulation right-click menu depend on the settings in the ''Simulation Menu Preferences'' dialog as described above.
| | A 3D UGrid of the project area is required. While the project can contain multiple UGrids, only one UGrid can be attached to each HGS simulation. The desired UGrid will need to be linked to the HGS simulation. |
| If any of the ''Multiple'' simulation commands are invoked, a dialog appears listing the simulations in this folder with toggle box next to each as shown. The user may then select which simulations should be included in this command.

|
| These optional commands should be self explanatory based on their name. In general, their function can be described as:
| | ===HGS Simulation Right-Click Menus=== |
| *A command that says '''Save Simulation''' generates the files for the numeric model simulation run, but does not save the project files. | | In the Project Explorer, right-clicking on a HGS simulation brings up a menu with several commands. Some of these commands are common to other Project Explorer In the Project Explorer, right-clicking on HGS simulation brings up a menu with several commands. Some of these commands are common to other Project Explorer right-click menus. Others are unique to the simulation right-click menus. Some of these unique commands are: |
| *A command that says '''Save Project''' saves the project such as mesh and map data, but doesn't generate the files needed for the simulation run. This command is typically used with the ''Save Simulation'' command. | | *"[[File:Mf6sim data.svg|16 px]] Simulation Data" |
| *A command that says '''Run Simulation''' runs the simulation. It is necessary to save the simulation files as part of or before using a run command. | | **'''Simulation Run Queue''' – Opens the ''Simulation Run Queue'' dialog which shows all current simulation runs. |
| All of the above applies equally to multiple simulations commands and single simulations commands.
| | *"[[File:Hgs-sim-folder icon.png|16 px]] HydroGeoSphere Simulations" |
| | ** '''New Simulation''' – Creates a new HGS simulation in the Project Explorer. This simulation will not contain any of the packages in any existing simulations and therefor the packages must be added. Also, creating a new simulation using this method requires linking a UGrid to the simulation. |
| | ** '''Save Multiple Simulations''' – Saves all HGS simulations in the project and exports all files needed for the model run. |
| | *[[File:HydroGeoSphere Simulation Icon.png|16 px]] Model |
| | **'''Simulation Control''' – Opens the [[GMS:HydroGeoSphere Simulation Control|''Simulation Control'']] dialog where the HGS simulation parameters are set. |
| | **'''Materials''' – Opens the HGS [[GMS:HydroGeoSphere Materials|''Materials'']] dialog. |
| | **'''Export''' – Saves out the simulation files. |
| | **'''Run grok''' – Opens the ''Run grok.exe'' dialog where GMS will generate the GROK file. The GROK file contains all of the information and instructions required for the HGS simulation. |
| | **'''Run phgs''' – Opens the ''Run phgs.exe'' dialog where the HGS simulation will run. |
| | **'''Run hsplot''' – Opens the ''Run hsplot.exe'' dialog which will post-process the simulation results for viewing. |
| | **'''Solution Plots''' – Opens the ''Solution Plots'' dialog which will display plots generated from the HGS solution. |
| | **'''Save Simulation''' – Saves the simulation and exports all files needed for the model run. |
| | **'''Save Project and Simulation''' – Saves the simulation and exports all files needed for the model run. |
| | **'''Read Solution''' – Loads the solution file for the associated simulation. Requires that the simulation has had a successful run. |

| ==Modeling Notes== | | ==HGS Executables== |
| *GMS allows multiple HGS simulations to exist in a single GMS project. | | Running HGS requires multiple executable. These include: |
| | * grok.exe – A pre-processor that uses the Grok input file containing the information and instructions for the HGS simulation. |
| | * phgs.exe – Performs the model simulation. |
| | * hsplot.exe – A post-processor that generates the simulations results. |
|
| |
|
| ==HGS Files==
| | Note: Executables are not shipped and installed with GMS, and as such users are required to install HydroGeoSphere in order to access executables. |
|
| |
|
| | Boundary conditions are defined on feature objects in GMS coverages. When the model is saved, GMS intersects the features with the UGrid to find the grid components (nodes, cells, faces, or segments) that should be associated with the boundary conditions, and writes the boundary conditions to the GROK file. Furthermore, when model native files are saved, the feature objects are intersected with the grid, similar to Map to Modflow. For boundary condition coverages, the type of feature object and the type of boundary condition determines the type of UGrid component (point, face, or segment) that the BC is mapped to. |
