5.2. Attach Geometry

There are no geometry creation tools in the Aqwa application so geometry must be attached to the hydrodynamic system. You can create the geometry from either of the following sources:

  • From within Workbench using DesignModeler. See the DesignModeler Help for details on the use of the various creation tools available.

  • From a CAD system supported by Workbench. See the CAD Integration section for a complete list of the supported systems.

Before attaching the geometry from either of these sources, you can specify several options that determine the characteristics of the geometry you choose to import by right-clicking the Geometry cell and choosing Properties. See the CAD Integration section for more details about the options, most of which do not apply in hydrodynamic analyses. Also see the General Modeling Requirements section for more information about the implications of Geometry import properties.

Note:  Aqwa only processes the Line Bodies and Surface Bodies in a geometry. Make sure that the boxes are checked for both of these Geometry options in the Properties view. You can attach a geometry that has no line or surface bodies, but Aqwa will not process the geometry.

  1. In an analysis system schematic, perform either of the following:

    • Right-click the Geometry cell and choose Properties

      OR

    • Select the Geometry cell in the schematic for a standard analysis, the from the Workspace toolbar dropdown menu, choose any option that includes Properties or Components.

  2. Check boxes to specify Default Geometry Options and Advanced Geometry Defaults.

Double-click the Model cell in the same analysis system schematic. The Aqwa application opens and displays the geometry.

DesignModeler is not running. Geometry is stored in an agdb file.

  1. Select the Geometry cell in an analysis system schematic.

  2. Browse to the agdb file from the following access points:

    • Right-click the Geometry cell in the Project Schematic, Import Geometry and choose Browse.

  3. Double-click the Model cell in the schematic. The Aqwa application opens and displays the geometry.

  4. If required, set geometry options in the Aqwa application by highlighting the Geometry object and choosing settings under Preferences in the Details view.

CAD system is not running. Geometry is stored in a native CAD system file, or in a CAD "neutral" file such as Parasolid or IGES.

  1. Select the Geometry cell in an analysis system schematic.

  2. Browse to the CAD file from the following access points:

    • Right-click the Geometry cell in the Project Schematic and choose Import Geometry.

  3. Double-click the Model cell in the Project Schematic. The Aqwa application opens and displays the geometry.

CAD Interface Terminology

The CAD interfaces can be run in either plug-in mode or in reader mode.

  • Attaching geometry in plug-in mode: requires that the CAD system be running.

  • Attaching geometry in reader mode: does not require that the CAD system be running.
