results.animate refused fluid steps because nothing deforms. A fluid step
instead plays its frames over time, the start-up transient from the field at
rest to the settled flow, the way an explicit step plays its frames. The
animation clock maps across the fluid frames once per cycle, and the fluid
results panel gains an Animate control beside its frame slider.
Part of #164.
The coloured obstacle surface samples the fluid beside each face, and
the solid cells carry no temperature, so a face held at 80 °C took the
mean of the fluid cells around it, which mixes in the cooler ones further
out: the heated-flow sample's bracket looked 50 °C beside 79.7 °C air. A
face whose thermal condition holds it at a temperature is now drawn at
that value, and the legend's range reaches it (the fluid never quite
does). Adiabatic and flux faces keep showing the fluid beside them.
Part of #157.
Demonstrate temperature slices and signed face-average wall heat with cool air passing an isothermal bracket. Register the original CPU-rendered gallery thumbnail and document the coarse transient setup.
Part of #157.
Route saved temperature through slices, obstacle surfaces, streamlines and both result views, with availability and model units shared by commands and the UI. Show signed obstacle heat histories per complete face area at the selected frame, leaving unrecorded times uncoloured and retaining the saved slice settings.

A changed form (Alt + scroll on the radius) is prepared 150 ms after it last
changed, the sphere drawn meanwhile; a region of more than 1000 nodes is not
previewed and moves on release.

With the form open a drag on the mesh grabs the node under the press and
moves it in the screen plane; Alt + scroll sizes the radius. The view draws
the original edges as a ghost under the moved ones, coloured by how each
element's scaled Jacobian changed, and the sphere; the form shows the region's
numbers live. Release runs mesh.node.move (one undo step), Esc cancels.

The window built a deformed copy of the model for every results plot,
which drops the geometry surfaces, so after a fluid solve the bracket
vanished and nothing else was drawn.
A fluid step's plot keeps the part as it is and draws the engine's flow
display through it (the same scene as the headless pictures): the
field on a slice, the part coloured by the flow beside it and
streamlines. The legend shows the field with its bands and the cells
of its extremes (Max/Min mark and turn the view to them); the results
panel swaps the deformation rows for the slice's normal and position,
the obstacles' colours, the streamlines and a frame slider, all
running the results.* commands. The status line describes the new
commands.
Part of #193.
After solve.fluid the results view had nothing to draw: a fluid step's
fields are per cell, the view only knew nodal fields, and the deformed
display it built dropped the geometry surfaces, so even the part
vanished.
A fluid step now has its own display (`engine::flow`, on render's
flow display data), shared by the headless pictures and the window:
the part drawn as it is, its faces coloured by the field in the fluid
beside them, the field on a slice through the domain and streamlines
seeded on the inlet face upstream of the obstacles, coloured by speed
when the legend shows velocity. It is first shown with velocity
magnitude on a slice through the middle, normal to the horizontal axis
across the flow.
New commands: results.slice {step, field: velocity|pressure, axis:
x|y|z|none, position, frame}, results.surface {step, show} and
results.streamlines {step, show, count, max_steps, seeds | line,
frame}, which replies with what it traced. results.contour takes
velocity and pressure for fluid steps (a new `pressure` field) with
the usual bands and legend clamp, and results.frame walks a fluid
step's frames. Streamlines leave the coming-soon list. Hostile
parameters are refused, and the counts are capped.
Part of #193.
Holes by diameter, fillets by radius, chamfers by distance and bosses by height below
thresholds, or under a geometry.check finding; the reply panel switches each feature
off and on (geometry.defeature) and defeatures the whole proposal.

geometry.faces.merge {name, faces} records a face merge in the model;
it is applied after the partitions whenever the design is opened or cut
again, undoes through the journal and is saved with the model. Meshers,
mesh.plan (features and rings see merge:<name>; a merged face is
prismatic when its B-rep faces are), checks and the viewport see one
face, drawn in the warm colour. geometry.faces.merge.delete removes it.

Use selection puts the selected design faces in the form as faces, in

engine::view::build (Style, Show, Palette) is the viewport's builder,
moved from ui-egui; ui-egui maps theme::Tokens onto a Palette and calls
it. Palette::LIGHT now equals the light theme's tokens. Test: the app's
scene and engine::view::frame's are identical for the same session.

XY Plot opens a section in the results panel: a quantity picker, the
series from results.xy plotted against the step's own axis with the
frame or mode shown marked (a click shows the nearest), nodal fields
read at the probed node, and Export CSV through results.xy. The energy
plot and the XY plot share one line-plot function.

geometry.check keeps its findings on the session (not an edit: not journalled,
saved or undone) while the checked design stays open; the picture and the app's
viewport draw the faces of small, sliver and near faces in the marker colour,
short edges as thick lines and a dot at each finding over everything. `mark:
false` or a clean check clears them.

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
corners use them; the remaining JSON fields hold geometry-specific shapes.

The context panel reads mesh.quality's reply as the counts (an area only for a surface mesh),
each metric's min, mean and max over its histogram (the bad end warm), and its worst element: a

and frames them.

results.export.csv runs solve.probe or results.reactions and writes their reply as an RFC 4180
CSV: a row per node (node, x, y, z and the quantities the step has, columns it does not have
left out) or per set with the total and the applied load; numbers in shortest round-trip form,
so they read back bit for bit. A stale result is refused. The results panel has Export CSV…
beside Reaction sums and under the probed node: the save picker, or the form without one.

results.contour takes range {min?, max?} (or "auto"), kept until the field changes: a
singular peak no longer squeezes the field into the bottom bands. Values above a clamped
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
follow the clamp too.

file.new replaces the session with an empty one: no design, mesh, definitions, results or
journal, nothing to save, the undo history empty. The File menu and Cmd/Ctrl+N run it, asking
first over unsaved changes. A sample name the app does not know (a typo, an old ?sample= link)
opens the samples to choose from, and the status names it.
