Sample Surfaces#

Sample surfaces are imported surface geometries used for extracting and analyzing flow field data at specific locations within the simulation domain.

Overview#

Sample surfaces allow you to use arbitrary surface geometries in the flow field to capture detailed flow properties. Unlike slices (which are planar and created in the GUI), sample surfaces can conform to complex shapes imported from external files, providing flexibility for flow analysis in regions of interest.

Sample surfaces are accessed through the Resource panel (see Top Bar), alongside geometry resources.

Note

A sample surface is a monitoring entity: a non-manifold surface used to measure quantities at internal locations. It is distinct from a baffle face, which is a non-manifold input face that the Geometry AI mesher removes or thickens during meshing preprocessing (see Remove baffle faces). The key difference: a baffle face is part of the input geometry processed by the mesher, whereas a sample surface is not represented in the mesh (the flow solution is sampled onto it).

Importing Sample Surfaces#

To import a sample surface:

  1. Open the Resource panel

  2. Select the Sample surface tab

  3. Click the Import button

  4. Select a surface geometry file to import

  5. The imported sample surface will appear in the Sample surfaces section of the Entities browser

Supported Formats#

Sample surfaces can be imported from standard surface mesh formats (e.g., STL, CGNS, UGRID).
