ADH boundary conditions can be created, deleted and edited via the ADH Boundary Conditions dialog. Boundary conditions are associated with a [[GMS:ADH Node, Face and Edge Sets|node, face or edge set]] to position them on the [[GMS:3D Mesh Module|3D mesh]]. Different boundary conditions apply to different "physics components" (also called "operations") as defined in the[[GMS:ADH Analysis Options|ADH Analysis Options]] dialog. GMS, however, allows you to define any boundary conditions regardless of the current settings in the Analysis Options dialog so that you can switch the analysis options and quickly try out different scenarios.

ADH
Model Info
Model type 3D, saturated and unsaturated, overland flow, 3D Navier-Stokes flow, and 2D or 3D shallow water
Developer USACE
v • e

ADH stands for ADaptive Hydrology/Hydraulics and is a model being developed by the US Army Corps of Engineers (USACE). An interface to ADH is being added to GMS. ADH is currently only available to individuals in USACE.

Display Options

GMS can draw symbols at mesh nodes, faces and edges to show where boundary conditions and node, face and edge sets are defined.

Node, face and edge sets

ADH uses node, face and edge sets to define locations on the 3D mesh where boundary conditions are located. These sets are created and deleted separately from the boundary conditions, which makes for great flexibility. GMS associates names with the sets for convenience and automatically numbers the sets when saving the ADH input files.

Creating sets

Node sets

A node set is simply that - a set of nodes. It is created by selecting boundary nodes using the Select Boundary Nodes File:Tool SelectBoundaryNodes.GIF tool and selecting the ADH|Create Set menu command.

Face sets

A face set is created by similarly but using the Select Boundary Faces File:Tool SelectBoundaryFaces.GIF tool.

Edge sets

An edge set is a collection of edges. An edge is defined as the line connecting two nodes on an element face. The edge is therefore described as a pair of nodes. Edge sets are created by defining a node string using the Select Node Strings File:Tool SelectNodeStrings.GIF tool and selecting the ADH|Create Set menu command.

Editing sets

Existing sets can be viewed and edited using the ADH|View Sets menu command. This brings up the View Sets dialog which lists the existing sets. Selecting sets in the list will cause the corresponding items on the 3D mesh to be selected and highlighted. The name of the set can be edited, but adding or removing items from the set is not allowed. If this type of editing is desired, you must delete the set and recreate it with the correct items.

Analysis Options

The ADH Analysis Options dialog is used to specify general and global model variables. For more information on each variable refer to theADH file format cards supported in GMS.

Output Control

The ADH Output Control dialog shows options for ADH output. The times at which ADH will generate output are listed in the spreadsheet. Times can be added or removed or pasted from another application. Times can also be added using the options under "Add times".

Constituents

Boundary Conditions

ADH boundary conditions can be created, deleted and edited via the ADH Boundary Conditions dialog. Boundary conditions are associated with a node, face or edge set to position them on the 3D mesh. Different boundary conditions apply to different "physics components" (also called "operations") as defined in theADH Analysis Options dialog. GMS, however, allows you to define any boundary conditions regardless of the current settings in the Analysis Options dialog so that you can switch the analysis options and quickly try out different scenarios.
