The dynamic model interface is available in SMS version 11.2 and later. It is primarily a tool for developers. The dynamic model interface provides a way to quickly generate an interface for a numeric model.

Dynamic dialogs are a quick way to generate dialogs without having to compile code. To add or delete a widget on a dynamic dialog, the user simply modifies the XML document. When the modified document is loaded, the new/modified dialog exists. The XML document defines the layout, behavior and the different dialog controls.

The dialog is divided into 2 sections, the tree and the widget view. The tree is on the left side of the dialog and it contains groups and items that represent data. Clicking on a group or item will result with the widget view being updated to match the selected tree or group item.

  • Order of the tree items and groups will match the order defined in the XML file.
  • Clicking on group will display all children items in the widget view.
  • Clicking on a single item will display associated widgets in widget view.
  • Tree item will also display the values in a non-editable field.
  • Unique_name use format: file::unique_name#value
  • Widgets or groups of widgets can be loaded from an outside file by using <link_to_xml>.
  • Multiple widgets when displayed on right side can be expanded/collapsed – TO BE DETERMINED
  • Can have nested groups
  • Keywords are words SMS has reserved in the schema and can not be used as unique names. All keywords will start with a “#”. Here is a list of available keywords:
  • #card_name
  • #geom_name – name of geometry as it shows up in the project explorer
  • #project_name
  • #value
  • #units
  • #xmdf_path – path inside the XMDF file
  • #file_name
  • #file_path
  • #sms_path – path in sms project explorer once inside a geometric item
  • #count (used for a widget in a table for counting the rows/columns)
  • #geom_guid

Projection keyword:

  • #horizontal_datum: NAD83 |NAD27|LOCAL
  • #horizontal_system: UTM|STATE_PLANE|GEOGRAPHIC|LOCAL
  • #horizontal_units: FEET|METERS|DEGREES
  • #horizontal_zone: 3104 etc
  • #vertical_datum
  • #vertical_units

Additional keywords are defined with the various custom control widgets.

Note: In changing from version 1 to version 2, all tags that were <custom_control_XXXX> were changed to <control_XXXX>.

Element <executable>
Info Represents a single executable used by the model.
Versions 2
Attributes none
Children executable_name, input_file, output_file, executable_order
Used by simulation
Example 1 
<executable>
   <executable_name>SRH 2D</executable_name>
   <input_file>
     <file_ref>caseFile</file_ref>
     <export_location>"%s", #project_name</export_location>
     <command_args>” -%s", #file_name</command_args>
     <execute>”%s”, #executable_name</execute>
   </input_file>
   <executable_order>1</executable_order>
 </executable>
Example 2 In the following example, one instance of the numeric model is executed per coverage. A file will be exported per coverage and no command line arguments are used when launching the model. 
<executable>
   <executable_name>SRH 2D</executable_name>
   <input_file>
     <process_each_coverage>
       <file_ref>caseFile</file_ref>
       <export_location>"%s/%s", #geom_name, #project_name</export_location>
       <execute>”%s - %s”, #executable_name, #geom_name</execute>
   </process_each_coverage>
   </input_file>
   <executable_order>1</executable_order>
 </executable>
Example 3 In the following example, only one instance of the numeric model is executed. A file will be exported per coverage and no command line arguments are used when launching the model. 
<executable>
   <executable_name>SRH 2D</executable_name>
   <input_file>
     <file_ref>caseFile</file_ref>
     <process_each_coverage>
       <export_location>"%s/%s", #geom_name, #project_name</export_location>
   </process_each_coverage>
   <execute>”%s”, #executable_name</execute>
   </input_file>
   <executable_order>1</executable_order>
 </executable>
