Derived Entities

Derived entities in Flow360 are entities that are created based on input geometry. These entities serve specific purposes in simulation setup, such as assigning symmetry in the model.

Farfield

Farfield entities define the outer boundaries of your computational domain. They are automatically generated based on your geometry and control the extent of the flow field simulation.

Symmetry

Symmetry entities are used to reduce computational domain size by utilizing geometric and flow symmetries. They allow you to simulate only a portion of the full domain when the flow physics and geometry exhibit symmetrical properties.

Symmetry planes are automatically created when using Farfield based on chosen method:

• Auto, a single symmetry plane named "symmetric" is created when using semi-spheres
• Quasi-3D, two symmetry planes named "symmetric-1" and "symmetric-2" are created on both sides of the thin disk
