4.4. Entities browser#

Entities are the fundamental components used for simulation setup in Flow360. They provide a hierarchical structure for organizing and managing CFD simulations, from geometry definition to results analysis.

Showing/hiding the entities browser: The Entities browser is shown by clicking the button in the top-right corner of the viewer area.

Entities visibility, highlighting (hover): As you hover the mouse over items in the Entities browser, they are highlighted in the viewer.

Entities browser modes: The Entities browser shows the Geometry, Mesh or Visualization items currently available in the viewer, and so it changes when the View mode is selected.

“View only” mode: The Entities browser has limited functionality when the Workbench is in “View only” mode. It can be used to show/hide elements and to browse the available entities and highlight them in the viewer. Creating and updating viewpoints is also supported at any time.

Draft Configuration: Modifications made in the Entities browser are saved as a Draft configuration. This draft can be retrieved and continued from the Project Tree view, allowing you to resume your work at any time.

Primary Assets#

The primary asset defines the starting point of your simulation workflow. Only one primary asset type is available per project, depending on how the project was created.

Geometry#

The root entity for CAD-based projects. Contains all geometric elements including edges, faces, and body groups. Geometry projects progress through surface meshing and volume meshing before simulation.

Surface Mesh#

The root entity for surface-mesh-based projects. Contains boundary definitions for specifying boundary conditions. Surface mesh projects require volume meshing before simulation.

Volume Mesh#

The root entity for volume-mesh-based projects. Contains zones and boundaries ready for simulation setup. Volume mesh projects can proceed directly to solver configuration.

Geometric Entities#

These entities define spatial regions and monitoring locations within your simulation domain. Their availability depends on the primary asset type.

Entity

Description

Geometry

Surface Mesh

Volume Mesh

Body group

Grouping of bodies from imported geometry files

Volume mesh slices

Cross-sections of the volume mesh for inspection

Volumes

3D regions for mesh refinement and flow analysis

Points

Monitoring locations for flow properties

Slices

Planar cross-sections for flow visualization

Sample Surfaces

Imported surfaces for flow data extraction

Derived

Auto-generated entities (farfield, symmetry planes)

Configuration Tools#

These entities are available in all project types and provide tools for visualization, organization, and scene management.

Viewpoints#

Saved camera positions and orientations for consistent visualization across sessions. Viewpoints can be created and modified even in “View only” mode.

Coordinate Systems#

Local reference frames for geometric transformations. Define custom coordinate systems with translation, rotation, and scaling relative to the global frame or other coordinate systems.

Environment#

Scene and background customization settings for the viewer, including background colors, gradients, and image uploads.

Entity Tags#

Custom labels for organizing and grouping entities. Tags support expression-based filtering for automatic entity selection.
