Ccs fuselage mesh¶
Commands of the ccs_fuselage_mesh 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.
CCS_FUSELAGE_MESH_GROWTH_RATE¶
Phase geometry, layout inline. Manual: SRC-003 p.301.
Ratio between the sizes of consecutive cells under the clustering scheme of the same direction. The manual states the value must be greater than zero and that bound is NOT enforced here, which is the standing treatment of the manual's stated positivity bounds (design decision of 2026-08-08).

CCS_FUSELAGE_MESH_GROWTH_SCHEME¶
Phase geometry, layout inline. Manual: SRC-003 p.301.
How grid nodes cluster along the direction. NONE spaces them evenly; SUCCESSIVE and REVERSE cluster toward one end and the other; DUAL-SIDED clusters toward both. The rate is set separately by CCS_FUSELAGE_MESH_GROWTH_RATE and means nothing under NONE.

CCS_FUSELAGE_MESH_PERIODICITY¶
Phase geometry, layout inline. Manual: SRC-003 p.301.
Number of times the clustering pattern repeats along the direction, so a value of 2 clusters the nodes twice over the same span. The manual states that solid fuselage shapes default to 1 in both directions and that the value must be greater than zero; the bound is not enforced here.

DEFAULT_CCS_FUSELAGE_MESH_SETTINGS¶
Phase geometry, layout inline. Manual: SRC-003 p.301.
Resets every mesh setting of the CCS fuselage in one parametric direction: subdivisions, growth scheme, growth rate and periodicity. One direction per call, so restoring both takes two.

DELETE_CCS_FUSELAGE_REFINEMENT_ZONES¶
Phase geometry, layout inline. Manual: SRC-003 p.302.
Deletes one axial refinement zone by its 1-based index, or every one of them when passed -1. The -1 is recorded here and not declared as all_sentinel because refinement zones are not an inventory the script builder tracks, so no index check exists for it to be exempt from. The plural name is the vendor's and applies to both forms.

DELETE_CCS_FUSELAGE_RELAXED_TE¶
Phase geometry, layout inline. Manual: SRC-003 p.302.
Deletes one relaxed trailing-edge boundary by its 1-based index, or every one of them when passed -1. Not declared as all_sentinel, for the reason given on DELETE_CCS_FUSELAGE_REFINEMENT_ZONES.

EXPORT_FUSELAGE_CCS_FILE¶
Phase geometry, layout inline. Manual: SRC-003 p.302.
Writes the lofted fuselage to a file instead of into the simulation. LOFT_TYPE_U is RADIAL here and LOFT_TYPE_V is AXIAL, which is not what the same two names mean on the wing commands, where they are chordwise and spanwise. THREE SOURCES ON THIS PAGE DISAGREE ABOUT THE ARGUMENT LIST, and the six recorded here are the signature heading's. Identically in all four editions, the heading prints six placeholders, the parameter table documents only four of them (MARK_TRAILING_EDGES and TE_GEOMETRY have no row), and the sample passes the four of the NEIGHBOURING command CAD_CREATE_FUSELAGE_MESH_FROM_CCS. The heading wins for two reasons that are about this page rather than about a general preference. The wing sibling EXPORT_WING_CCS_FILE prints the SAME six placeholders and documents all six in its table, so the six are the family's export signature and this table is missing rows rather than describing a shorter command. And the sample cannot be this command's own: it is the create command's sample with the name swapped, which is visible directly on the revolve sibling, where the copied sample passes arguments (a frame, an axis and two angles) that appear nowhere in the export heading. Registered for a probe as PLN-20260808-1730. CLOSE_ENDS accepts TRUE as well as OPEN and CLOSED, the contradiction the whole CCS family carries: the table states the two words and every sample passes TRUE, so refusing the sample's own value would refuse the only form the vendor has written as a runnable line.

NEW_CCS_FUSELAGE_REFINEMENT_ZONE¶
Phase geometry, layout inline. Manual: SRC-003 p.301.
Inserts extra grid nodes over an axial parametric interval. U0 and U1 are parametric positions between 0 and 1 with U1 greater than U0, and NUM_PTS is the count of nodes added inside that interval rather than the total across it. Neither the range nor the ordering is enforced here.

NEW_CCS_FUSELAGE_RELAXED_TE¶
Phase geometry, layout inline. Manual: SRC-003 p.302.
Marks a strip of the fuselage as a relaxed trailing edge, where the solver applies the Kutta condition with a relaxed formulation. U is the radial parametric location of the boundary and V0 and V1 its axial parametric limits, all between 0 and 1 with V1 greater than V0. The bounds are not enforced here.
