Define solubilizing active-drop cases with explicit scales - #1
Conversation
Keep the pipe and channel drivers self-contained. Apply periodic boundaries in the requested directions, exclude the drop phase from solid walls, and preserve continuous centroid displacement across periodic seams. Check actual case initialization and solid cleanup without advancing the solver, and test repeated periodic crossings.

Review: Restore standalone cases with periodic, non-wetting boundaries (#1)
Summary
Standalone pipe and channel drivers replace the shared dropMove-embed.h. dropMove.c is periodic in both directions (periodic(right) / periodic(top)), which updates existing fields and Period (basilisk-source/src/grid/cartesian-common.h:1059). Confined cases are periodic left/right only, with no-slip non-wetting embedded walls (f[embed]=dirichlet(0), solids f=0 and negative d) and impermeable species (cL[embed]=neumann(0) from embed.h:715 / embed.h:730). Pipe keeps axi.h with origin y=0 (bottom = symmetry axis). Axial centroids unwrap about the previous centroid; confined y is not unwrapped. Contract tests cover seam continuity and actual-case boundary/solid probes. No verified P0/P1.
Findings
P3: see the comment #1 (comment) by coderabbitai
Missing Tests
None blocking. test_periodic_centroid.py extracts the production moment formulas; test_case_boundaries.py compiles the actual drivers with the time loop replaced by a bounded inspect. run-tests.sh now discovers test_*.py.

Review: Restore standalone cases with periodic, non-wetting boundaries (#1)
Summary
Docs-only delta from previously approved 8c6fc850. AGENTS.md now lists embed-channel-geometry.h (confined_geometry()), standalone drivers, periodic vs confined topology, non-wetting solids, and the new centroid/boundary contracts. Reused channel/pipe drivers still unwrap only the periodic axial coordinate; transverse y stays physical. Cached P0/P1 revalidated: none. No verified P0/P1.
Findings
P3: see the comment #1 (review) by coderabbitai
Missing Tests
None blocking. Behavioural coverage is unchanged on this head.
Verification Steps
bash testCases/run-tests.sh(centroid contracts need systemcc; case-boundary probes need pinnedbasilisk/src/qcc)bash testCases/run-embed-tests.sh
Expose Reynolds, capillary, Peclet, activity and surface-tension coupling groups with material ratios and derived mobility comparisons. Use reconstructed interface area for emission, including axisymmetric weighting and aligned interfaces. Document the General programme and its solubilizing interpretation. Preserve standalone cases and reject retired Oh input consistently.

Reject non-finite L0.
When L0=inf, param_double() accepts the value and L0_param > 0. evaluates true. The code then calls origin(-inf, -inf), so domain initialisation receives non-finite coordinates. Add a finite check.

Assert that retired-Oh rejection does not create a scan directory.
PeScan.main returns status 2 before scan_dir.mkdir(...), but the test asserts only the status. Use a unique tag and assert that simulationCases/pescan-<tag> does not exist after the call. Otherwise, a directory-creation regression can pass the Python contract test.

Review: Define solubilizing active-drop cases with explicit scales (#1)
Summary
+8278/−2970 across 50 reviewable files. Explicit Re, Ca, Pe, GammaSlope, AcNum and inner/outer material ratios replace retired Oh; the three standalone drivers share PLIC source AcNum/Pe and derived Oh=sqrt(Ca/Re). Periodic planar dropMove.c plus confined channel/pipe keep no-slip non-wetting walls (f[embed]=dirichlet(0)) and impermeable species (cL[embed]=neumann(0) from embed.h:730). periodic(right)/periodic(top) are core (cartesian-common.h:1059). stokes=false retains convective inertia (centered.h:73). Cached P0/P1 revalidated: none. No verified P0/P1.
Findings
P2 — Retired-Oh PeScan test does not assert the scan was not created
File: testCases/test_pescan.py:148
Layer: Tests
Impact: A regression that creates simulationCases/pescan-* before returning 2 would still pass.
Detail: test_main_rejects_legacy_oh_before_creating_scan writes Oh=1 and checks only status == 2.
Fix direction: After PeScan.main(...), assert the tagged scan directory / results.json does not exist.
Missing Tests
None blocking. test_dimensionless_model.py maps the public groups onto rho/mu/cL.A/cL.D and mobility diagnostics; activity-source-budget.c checks circle/sphere PLIC area and the face-aligned fallback; embed tests compile that budget for pipe and planar.
Verification Steps
bash testCases/run-tests.sh(centroid contracts need systemcc; case-boundary and dimensionless-model probes need pinnedbasilisk/src/qcc)bash testCases/run-embed-tests.sh
Explain the equal-viscosity origin of the surface-tension slope and distinguish it from the momentum coefficient Re=Ca/Oh^2. Document the complete momentum balance and regenerate the model pages.

Review: Define solubilizing active-drop cases with explicit scales (#1)
Summary
One-commit docs delta from previously approved 38fe39fb. src-local/active-drop-model.h now spells the planar mobility provenance (GammaSlope=2(1+\lambda)=4 at equal viscosities), the identity Oh=sqrt(Ca/Re) / Re=Ca/Oh^2, and that the momentum coefficient is Re with both inertia terms retained (stokes=false, centered.h:73). README.md lists embed-channel-geometry.h and restates the same contract. Generated .github/docs HTML tracks those docs. Executable drivers, source, and tests are unchanged on this head. Periodic planar dropMove.c plus confined channel/pipe keep no-slip non-wetting walls (f[embed]=dirichlet(0) from embed.h:715) and impermeable species (cL[embed]=neumann(0) from embed.h:730). periodic(right)/periodic(top) are core (cartesian-common.h:1059).

Summary
Define three standalone solubilizing active-drop cases: a fully periodic planar drop, a planar channel and an axisymmetric pipe with periodic axial boundaries. Embedded walls impose no slip, dispersed-phase exclusion and zero species flux.
The chemical field represents emitted, surface-tension-increasing solute. Explicit Re, Ca, Pe, GammaSlope, activity and material ratios replace the implicit normalization; Oh is derived. The source coefficient is AcNum/Pe, with PLIC interface area and axisymmetric weighting. Planar and spherical mobility comparisons are reported separately.
This is the primary codebase for the General active-drop programme; finite exterior fuel and reduced stochastic response remain separate models.
Validation
Twenty Python/source-probe tests and the geometry, tracer, wall-flux and source-budget checks pass. Circle/sphere source-area errors decrease under refinement. All three drivers compile, and bounded actual-step checks pass. Periodic centroid tracking is tested across repeated domain crossings.
Limitations
No micelle kinetics, solubilization-driven mass loss or contact-line evolution law. Interface-support cells must remain separated from embedded cut cells; the gap guard stops contact. The whole-field concentration extension and sharp exterior-flux limit remain unverified; mobility diagnostics do not establish confined onset or physical wall attraction/repulsion.
