Volume sections¶
Commands of the volume_sections chapter of the database, 10 entries. The status words are defined once, on the compatibility matrix, which says what each rests on and what the script builder does with it. Read it before this page: broken and removed are refusals, so a row here can be telling you the emitter will not write that command for that version.
CREATE_NEW_CIRCLE_VOLUME_SECTION¶
Phase analysis, layout inline. Manual: SRC-003 p.366.
Annular flow-field section with IPTS radial and JPTS azimuth segments between the inner and outer radii; the natural plane for slipstream surveys behind an actuator disc.

DELETE_ALL_VOLUME_SECTIONS¶
Phase analysis, layout bare. Manual: SRC-003 p.367.
Deletes every volume section, where DELETE_VOLUME_SECTION takes one index. A separate command rather than a sentinel of that one.

EXPORT_VOLUME_SECTION_2D_VTK¶
Phase analysis, layout inline. Manual: SRC-003 p.367.
Exports one volume section as a 2D ParaView file, the path on the next line. THE 2D AND 3D VTK EXPORTS ARE DIFFERENT COMMANDS WRITING THE SAME EXTENSION. EXPORT_VOLUME_SECTION_VTK, already in this chapter, writes the section as a slice through a 3D field; this one writes it as a planar dataset. A file name cannot distinguish them, so a reader of an output folder cannot tell which command wrote what.

VOLUME_SECTION_BOUNDARY_LAYER¶
Phase analysis, layout inline. Manual: SRC-725 p.365.
Toggles boundary-layer induction on one volume section (index greater than 0). Documented in 26.1 only (SRC-725 p.365); the command disappeared from the manual at 26.12 with no successor in the Volume Sections family.

| 26.120 | removed | absent from the 26.12 manual: the Volume Sections family (SRC-003 pp.366-367) no longer lists the command and the Script Index does not carry it; no replacement documented |
VOLUME_SECTION_WIREFRAME¶
Phase analysis, layout inline. Manual: SRC-003 p.366.
Draws one volume section as a wireframe rather than as a filled contour. A display setting, but phase analysis rather than control: it names a volume section, which exists only once one has been created. The parameter table documents the INDEX row alone and says nothing about the second placeholder, which the heading prints and the sample passes as ENABLE. Recorded from the heading and the sample, which agree with each other.
