A partition intersects the body with a box on each side of the plane as
large as the body itself. SolidCraft's split_by_plane uses boxes several
times larger, and its boolean then put the cut up to 1.8 um off the plane
on the enclosure's air, so the cut faces were not recognized and the cells
did not close. A plane along a face of a body it cuts, or a cell whose
boundary does not tessellate into one a mesher takes (a cut through a
hole's axis), is a warning naming the partition, the body and where.

Deleting, suppressing or editing a partition (or its datum), or cutting a
meshed body, removes the meshes of the bodies that are gone, reported as
replaced, in the same undo step. model.check lists meshes of partition
cells the open design no longer has (a model saved before the cut
changed), and mesh.clear removes them, or the meshes of named bodies.

A node on the secondary surfaces of two ties (a chip's underside and its
sides, a cut face and an outer face) got one constraint per tie. When the
main nodes of one follow the other's main surface, the second constraint is
nearly the first again, and eliminating it divided by round-off: the Pi 5
heat model put 21.9 W more in than its 8 W. Such a node now follows the
main faces of all its ties together (balanced to 5e-11 of the power), a
node following a node that follows it back (a tie each way on one
interface) is an error naming both ties, and a tie row that still nearly
repeats the constraints before it is an error naming them.
mesh.cells ties one way by a fixed order of the cells (hex main to tet)
and makes one tie per tied cell, tie_<cell>, replacing the ties an earlier
run made, so its own ties never hold a node twice.

hex_mesh_swept_cells lays out one cross-section for several cells: every
cell's walls (its cut faces included) are imprinted together, every cell's
levels are levels of all, one interval assignment and one set of layers,
and each region of each level interval is filled by the cell it lies in.
Cells meet node for node across every cut, T-junctions included.
mesh.cells sweeps the cells of each design body together first and meshes
cell by cell only what does not sweep together (saying why); the reply
gives every cell's volume, scaled Jacobian and edge ratio.

split_by_plane gives one body per side, which may hold several shells when
the side falls apart; every lump is now its own cell (B/a1, B/a2), at every
cut, as the partition docs promise.

Four field kinds in the schema, each checked and described in JSON Schema: labels (nodes or
elements, typed as 1-5, 8 with Use selection taking the viewport's picks), points (rows of
x, y, z, added and removed), multi (checkboxes: coupling DOFs, step output) and number or
auto (the deformed scale). Node and element lists, probe and Delaunay points and block

results.contour takes range {min?, max?} (or "auto"), kept until the field changes: a

maximum go to an extra band drawn in the over colour, split exactly at the clamp; the legend
shows that band up to the true maximum and says it is clamped. The results panel has Legend
max/min (Auto or a value), the MCP show_results tool a range argument, and headless pictures

nodes only they use); Session::hidden_elements names them, so the viewport,
probing and headless pictures skip hidden bodies (#365).
- A solve summary's applied and reaction totals set the round-off of
cancelling sums to 0 (#319).
- results::principal for the probe's principal stresses (#329).

unit system (mm, MPa, N, N·mm, mJ, mW, °C or K); Field::title puts it in the

- A solved step's result stays current through edits that leave what it reads
alone (Model::step_inputs: other steps and what only they use), and comes
back current on undo (#318).
- Session::step_glyphs: the symbols of what a solved step used, for drawing
over its results; no load arrows on a frequency step's modes (#327).
- Nonlinear static steps open deformed at true scale like explicit ones, and
their automatic scale is 1 (auto_scale, shared by the viewport and the

sets, as its form says (#328).

SolidCraft names the pieces of a split body by stacking suffixes
(Bracket (1) (1)' (1)). On opening a design, the pieces of one body are
named <body>.1 … <body>.N, ordered by centroid, so the tree, tooltips,
forms and picks read as one part with numbered cells.

shows the step, stage, count and elapsed time with a bar when bounded, OK
waits while it runs, and the status sums it up (elements, smallest angle,
time) (#322, #357).
- Over the control channel such a command is a job too: answered when it
ends however long it runs, or at once with wait: false, then job.status,
job.wait, job.cancel; ui.inspect gives job; MCP waits for it (#367).
- A command that cannot run yet lists what it misses in the context panel,
each with a button to the command that provides it (#323).
- A cancelled or refused solve stays in its workspace (#324, test).
- A mesher form starts from the parameters of the mesh it would replace (#343).
- Seed Edges and edge/vertex/face datum points switch the selection filter
while open and restore it (#341).

Delaunay refinement split a boundary face edge at its midpoint even when that
midpoint lay inside the diametral sphere of a feature edge beside it. Each such
split halves the face vertices' distance to the curve, so they piled up against
it (the heated bracket grew face vertices 0.016 mm from a 4 mm-sized edge), the
improvement schedule could not lift the tetrahedra there to its target, and
inserted vertex after vertex around them: 29257 elements and about two minutes
to open instead of 23641 and 6 s. The SolidCraft pin move (4c91f9b) added one
interior vertex to the bracket's end faces, which changed the CDT enough to
expose it.
Following Shewchuk (1998), an encroaching midpoint now splits the encroached
feature edge instead.

The desktop app installs the crash reporter and a log file at start

the window's commands (background jobs included) and every control
request's method, and ends the journal on a clean exit. A start after a
crash asks: "FieldCraft closed unexpectedly", Report It… or Not Now.
Help › Report a Bug (also Tools › Help and ui.start
diagnostics.bug_report) shows exactly what the GitHub bug form will be
filled with: the version, the OS, the last error, and for a crash where
it happened. Share my session adds the replayable commands, Include the

through the system's opener; files to attach are saved to

unclean exit found at the next start (abort, segfault, a crash in a
graphics driver, a kill: what #248 needs), a report with the model the
journal starts from (autosave, file or a copy) and the commands since,
the last control request and the dead run's log lines. Reports are
bounded, deduplicated by signature and replayable (crash::replay, with
writes confined to a scratch folder). The crash folder follows the
automation temp area in --control and CI runs.
logfile: a small size-rotated file logger behind the log facade.
bug_report: GitHub bug-form drafts. Version, OS and what happened by
default, home folder shown as ~; the command journal only with Share my
