SMS:ADH 2D Shallow Water Flow
"ADH is a state-of-the-art ADaptive Hydraulics Modeling system developed by the Coastal and Hydraulics Laboratory (CHL), ERDC, USACE, and is capable of handling both saturated and unsaturated groundwater, overland flow, three-dimensional Navier-Stokes flow, and two- or three-dimensional shallow water problems." [1]
Information about the ADH model can be found at the ADaptive Hydraulics Modeling HomePage.
Functionality
Graphical Interface
The model was initially included in the 9.2 version release and was overhauled for the 10.0 version release, however it is available only to the model developers. We are continuing to develop an interface to allow SMS users to utilize ADH for 2D shallow water flow and sediment transport analysis.
Files
An ADH simulation is defined using three main files: mesh geometry (*.3dm), boundary conditions (*.bc), and hot start conditions (*.hot). ADH expects a 3-dimensional mesh geometry since it can solve 3D models, but SMS will only interface the 2D capabilities and will therefore only read and write 2D entities in the *.3dm file. A generic SMS mesh geometry file (*.2dm) can be used by ADH if the extension is changed to *.3dm. To facilitate handling the ADH files, SMS creates a simulation file (*.sim) which lists the individual files. Opening the *.sim will load the ADH files in SMS.
Each file is a card based text file that can be viewed and edited by a text editor (i.e. Notepad).
- Mesh geometry file (*.2dm/*.3dm)
- Boundary condition file (*.bc)
- Hot start file (*.hot)
- Boat definition file (*.bt)
Dialogs
SMS provides the capability to view and edit model parameters via dialog boxes specific to the ADH interface. The following are descriptions of important windows accessible from the ADH menu and right-click menus.
- Model Control
- Boundary Condition Assignment
- Material Properties
- Hot Start Initial Conditions
- Model Check (currently unavailable - under development)
- Boundary Layers (currently unavailable - under development)
- Run Model
