31.1.3 Facet Values

Facets can be created on preprocessing surfaces and postprocessing surfaces.

Facet Values on Zone Surfaces

The interior facets on a zone surface are associated with two cells ( c0 and c1). The values of a specified variable on such facets are computed as the average of the two cell values of the selected variable.

The boundary facet values of a specified field variable on a zone surface are computed from the boundary condition provided by the user.

Facet Values on Postprocessing Surfaces

Each facet on a postprocessing surface is associated with a cell. The values of a specified variable on facets are the same as the cell values of the selected variable in the associated cells (this includes iso surfaces, planes, lines, points, rakes, quadric, etc.).
