Solver export¶
Commands of the solver_export chapter of the database, 9 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.
DELETE_BL_VELOCITY_PROFILE¶
Phase export, layout bare. Manual: SRC-750 p.377.
Discards the boundary-layer velocity profile. The page states it takes no parameters, so it clears whatever EXPORT_BL_VELOCITY_PROFILE last produced rather than addressing one profile of several. First documented by the 26.122 edition.
| Version | Status | Evidence |
|---|---|---|
| 26.122 | documented | SRC-750 p.377, the first edition to document it |
| 26.123 | documented | SRC-751 p.377, unchanged from SRC-750 p.377 |
| 26.124 | documented | SRC-752 p.377, the SRC-751 file, carried from 26.123; not run on 26.124 |
EXPORT_BL_VELOCITY_PROFILE¶
Phase export, layout inline. Manual: SRC-750 p.377.
Exports the boundary-layer velocity profile through the wall at one point, given in the named coordinate system, with the file path on the line after the command. First documented by the 26.122 edition. The page gives no units for X, Y and Z and no length unit appears in the call, so they are the coordinate system's own, which for the reference frame is the simulation length units. Recorded as unitless floats rather than given a unit the manual does not state. IT IS INTERACTIVE AND CANNOT BE USED IN AN UNATTENDED RUN, measured on 26.122 on 2026-08-17 and recorded in reports/RPT-027_boundary-layer-across-a-proximity-gap_2026-08-17.md. The command opens a modal window carrying a plot of velocity against height above the surface and a Done button, and script processing STOPS there until a person dismisses it. Under -hidden, with both streams redirected. A batch run reaching it waits forever, and the wait is indistinguishable from a hang unless somebody is at the machine. No status is written from that. It is a fact about the interface rather than a refusal by the solver, which is a different claim from the one
brokenmakes, and a status rests on a committed probe report rather than on a hand run (invariant 3). What it does mean is that a measurement wanting the boundary layer needs another instrument, and RPT-027 used the integrated viscous drag instead.

EXPORT_SOLVER_ANALYSIS_TECPLOT¶
Phase export, layout param_lines. Manual: SRC-003 p.352.
Exports the Tecplot .dat file for all initialized boundaries, one FEPolygon zone in the reference frame with its values per node (RPT-074). Since 0.28.0 no campaign workflow emits it: the surface Tecplot of a point is written by the package from the VTK export, cell-centred, in the reference frame (G45). A hand-written script still reaches it through helpers.export_results.

EXPORT_SOLVER_ANALYSIS_VTK¶
Phase export, layout param_lines. Manual: SRC-003 p.352.
Exports the VTK file. SURFACES takes -1 for all boundaries or a count followed by one index per line. Legacy ASCII polydata with one value per polygon, written in the analysis loads frame, the points and the velocity components alike, each as a point is written, the frame's origin included (RPT-074 and its addendum). A campaign's Tecplot surface is written by the package from this export (G45).

SET_VTK_EXPORT_VARIABLES¶
Phase export, layout payload_lines. Manual: SRC-003 p.352.
NUM_VARIABLES takes -1 for all variables; otherwise one variable name follows per line. The CP argument is flagged for depreciation in favor of CP_REFERENCE and CP_FREESTREAM (SRC-003 p.352); the emitter warns when CP is requested.
