Slices

Slices#

Slices are two-dimensional planes used to extract and visualize flow field data in Flow360. They are essential tools for analyzing flow characteristics at specific locations within the computational domain.

Available Options#

Option

Description

Normal

Three-dimensional vector specifying the orientation of the slice plane

Origin

Reference point that lies on the slice plane

Detailed Descriptions#

Normal#

A three-dimensional vector (X, Y, Z) that defines the direction perpendicular to the slice surface.

  • Default: (0, 0, 1)

  • Example: (1, 0, 0) for a YZ plane

Note: The vector must be non-zero and will be normalized internally.

Origin#

A point in 3D space (X, Y, Z) that defines where the slice plane is positioned.

  • Default: (0, 0, 0) m

  • Example: (0, 0, 0) m

Note: Coordinates are specified in m, cm, mm, ft or inch.

Note

For configuring slice data outputs, see Slice Output. For cross-sections of the volume mesh, see Volume Mesh Slices.

❓ Frequently Asked Questions

  • How is the data interpolated onto the slice?

    The flow field data is interpolated from the three-dimensional computational mesh onto the two-dimensional slice plane.

  • Does the slice resolution depend on the mesh?

    Yes, the resolution of the visualized data on the slice depends on the resolution of the underlying computational mesh.
