Entity Tags

Entity tags provide a flexible way to organize and group entities across your simulation project for easier management and selection.

Overview

Entity tags allow you to apply custom labels to entities in your project, enabling:

• Logical grouping of related entities regardless of their type

• Quick selection of multiple entities with the same tag

• Organization of complex simulations with many entities

• Filtering and searching for specific entity groups

Creating and Managing Tags

Creating a New Tag

1. Navigate to the Entity tags section in the Entities browser

2. Click the “+” button to create a new tag

3. Configure the tag parameters

4. The tag is now available and entities matching the expression are automatically tagged

Tag Parameters

Parameter	Description
Name	A descriptive name for the tag
Description	Optional description explaining the purpose of the tag
Type	The entity type to tag (e.g., Surface, Volume, Point, etc.)

Tagging Entities via Expression

Tags can automatically include entities based on expressions. This allows you to dynamically tag entities that match specified criteria.

Expression Builder

Each expression condition consists of:

Component	Description
Property	The entity property to filter on (e.g., Name)
Operator	The matching operator: matches or not matches
Value	The pattern to match against (supports wildcards, e.g., *wing*)

Combining Conditions

• Use the And / Or toggle to control how multiple conditions are combined:

  • And - Entity must match ALL conditions

  • Or - Entity must match ANY condition

• Click + Add to add additional filter conditions

• Click the trash icon to remove a condition

Applying Tags Manually

Tags can also be applied to individual entities through:

• The entity’s properties panel (via the Tag field)

• Selecting an entity and assigning it to an existing tag

Use Cases

Boundary Condition Groups

Tag all surfaces that share the same boundary condition type for easy identification and modification.

Output Selection

Tag entities that should be included in specific output configurations (e.g., all surfaces for force calculation).

Refinement Regions

Tag volumes and surfaces that require similar mesh refinement settings.

Component Organization

In multi-component assemblies, tag entities belonging to each component (e.g., “fuselage”, “wing”, “tail”).
