Review issues — fhsim_marine_elements

Findings from code review that await an owner decision or an implementation. Each issue is one file in issues/details/, which holds the evidence, the effect, the possible fix, the test that would prove it and the risk. Resolved issues are kept in issues/resolved/ so that their numbers are never reused. Issues that concern a SimObject are also shown on that model's documentation page. Audit notes that are not issues are in issues/notes.md.

How to work an item

1. Reproduce the Evidence at the file:line given in the detail file, at HEAD.
2. For a blocked item, get the owner's answer to "Decision needed" first, then set Status to ready.
3. Write the proving test, apply the fix, check the Risk paragraph.
4. git mv the file to issues/resolved/, add a **Resolved:** <commit>, <date> paragraph after the table, delete the matching \xrefitem reviewissue "Review issues" "Review issues" \ref fhsim_marine_elements_issue_<ID> lines from the headers, rerun the script and commit it all together.

New issue: --new <slug> "<title>", or add issues/details/<slug>.md with the metadata table but no ID row; the script assigns the next free number, writes the heading and renames the file to <TAG>-<ID>-<slug>.md.

Corrected 2026-10-04 by fhsim_environment 2f4335f (fix, tests, doc) and e2c49fd (ENV-0106, CHANGELOG): the clamp at Re = 1 (Cd = 11) underestimated Stokes-range drag about 3× against the digitised White/Wiley curve (33.3 at Re = 0.2, 16.4 at 0.5). White's correlation now applies below Re = 1 too (30.2 at 0.2, 16.9 at 0.5, 11 at 1), down to the floor kMinimumReynolds = 1e-6 (Cd = 1 + 1e5, slope 0), which only keeps Cd finite in axial flow; the normal drag ∝ |v_n|^(4/3) tends to 0 regardless, and force and Jacobian stay finite for v_n = 0 and 1e-20 m/s. CylinderHydro_Test red on 3 tests before, all pass after. fhsim_base e0aa58f: CableAddedMass.NeutralRopeFollowsTheWaterAcceleration made drag negligible with a 1e-9 m hydrodynamic diameter, where Cd is now about 1800, and went red (7.9e-6 against 2.6e-6 m/s²); it takes 1e-15 m (below the floor). No baseline moved: here full ctest (2 entries) and the 20 VALIDATION cases, fhsim_base (191) and fhsim_fishery (1 entry) pass, all rebuilt against the corrected header..

• MARE-0346 (ARCHITECTURE) — NetWakeCaster holds a copy of the marching wake build that fhsim_environment now owns. Resolved: 3c7f08b, 2026-10-02 (batch B4, design R5: NetWakeCaster wraps fhsim_environment's WakeCaster (ENV-0093) over a panel adapter; net_wake::WakeSettings, WakeEvaluation, ReadWakeSettings are the environment's; the Norm/Require/Format copies are gone (fhsim_environment WakeCommon.h, now installed). Test EnvironmentForwarders.TheNetWakeSettingsAreTheEnvironmentOnes_MARE0346 failed before (B4-me-red.log, 2 of 3 checks), passes after; NetWakeCaster_Test (43) unchanged and passing; characterisation dumps C1 to C9 identical to the post-R135 reference /tmp/char/B4-base).

Resolved: c65a30d, 2026-10-02 (batch B7, B6 review P2 and design §2.1 C3 (b): the net headers, NetWakeCaster.h, the methods manual and the user guide name NetFlowInteraction, BodyWake::Update and BodyWake::Query(); NetWakeCaster is documented as kept for its tests and outside code and removed in 5.0; WakeEvaluation None is documented for both nets; the bench comment names fhsim_environment's WakeCaster. Test NetWakeCaster.WithoutAPrivateFieldTheNetCastsItsUnshadedForce_MARE0348 pins the documented None behaviour of a net; it passes with fhsim_environment from ENV-0094 on, so it has no red run).

• MARE-0349 (DOCUMENTATION) — The nets' and bodies' docs describe the held wakes without the live blend weight of R136, and MARE-0122 does not record what R135 and R136 did to its collapse. Resolved: 677389d, 2026-10-02 (batch B8, owner ruling R136, with fhsim_environment ENV-0099 and marenv MENV-0066: the C3 parameter ExternalWakeUpdate in NetStructure.h (class comment and @addoption), NetStructureWithConstraints.h, Disk.h, Sphere.h, doc/user/main_marine_elements.md and doc/user/net_hydrodynamics_methods.md says the held samples take the blend weight of each evaluation's time; MARE-0122 gains a note with the S6 numbers of B2, B3 and B8; CHANGELOG.

• MARE-0350 (ARCHITECTURE) — NetFlowInteraction::FlowAt asks the panel adapter for a point's nodes through two virtual calls at every evaluation. Resolved: 63591fb, 2026-10-03 (batch C-perf: NetFlowInteraction::FinalSetup holds each sample point's nodes, from PanelSourceSet::SamplePointCarriers, and FlowAt reads them; the net's topology is fixed before FinalSetup.

• MARE-0351 (ARCHITECTURE) — The library keeps copies and forwarders of the laws and the casting path fhsim_environment now owns. Resolved: 417126a, 992af6a, 7194757 (both reverted by 1d82b7b), c310ee3, 7a74300, 2026-10-04 (feature fluid-body-interaction batch B3). 417126a: the library includes fhsim_environment's laws and casting path; the copies, forwarders and duplicated tests are deleted (src/hydrodynamics/, net/NetSolidity.h, net/DiskDrag.h, the drag of DiskBase.h and the forwards of SphereBase.h, cable/subroutines/CableSurface.h and CableHydrodynamics.h, net/ExternalWakeCutoff.h, net/BodyFlowInteraction.*, net/NetWakeCaster.*); Net/Sphere/Net/Disk hold SphereCaster/DiskCaster and BodyFlowInteraction; NetWakePanels<Net> replaces the two adapters, with a shared Environment lookup naming the class; the net cables' edge-on disc drag is disk_hydro::DragForceTangential (the face-on annulus of MARE-0074 stays inline: disk_hydro::DragForceNormal has the face area π/4 D (D − d/π), owner question whether fhsim_environment should gain the annulus); RbCable/Cable takes NormalDragCoefficientWithLift. Bit for bit except the rounding of the Net/Sphere Jacobian (owner: bit identity dropped); no baseline moved. Tests 422 (22 disabled) → 263 (11 disabled), 0 failures; the 20 VALIDATION cases pass. 992af6a (owner ruling 2026-10-04, since withdrawn): CableSegmentWaterForce.h, CableRMWaterLoad.h (water branch) and ElementWaterLoad.h took Cd |v_n| v; 7194757 moved the SimObject.RundDorg_Smoke baseline for it. Both are reverted by 1d82b7b (owner ruling 2026-10-04, superseding: the independence principle); no result change remains from them. c310ee3: tests CableModelsHydrodynamics.{TrawlCable,RbCable,RbCableElement}DragFollowsTheIndependencePrinciple_MARE0351 replace the tests of the withdrawn law: red with 992af6a's assembly (3 failed), green on the restored one. SimObject.RundDorg_Smoke is checked at 30 s, settled, instead of 1 s in the clump's initial fall (owner-accepted recommendation; line-end direction asserts restored, the mirror symmetry kept, the settled end forces pinned: Line1ForceVector (200.667, −37.4005, 53.6619) N, Line2 its mirror, MainForceVector x −654.697 N, z 4945.58 N; 7a74300).

• MARE-0352 (KNOWN-LIMITATION) — The net cables, cable/Cable and CableBranched apply the normal drag to v_n only, unlike the 2026-10-04 cable drag ruling. Resolved: won't fix, 2026-10-04. The ruling it would have extended (the normal cable drag Cd·|v_n| on the full relative velocity v) was withdrawn the same day; the superseding owner ruling is the independence principle, normal drag Cd·|v_n|·v_n plus a separate axial skin friction Ct·|v_t|·v_t (DNV-RP-C205, Morison, OrcaFlex), and the three assemblies that had taken the withdrawn law are reverted to it (MARE-0351). Both models named below already follow it: CableElBasics applies the normal drag to each end's v_n and the skin friction |v_t| v_t to the element mean (src/cable/subroutines/CableElBasics.cpp:451-470), the air branch of RbCable/Cable takes Cd |V_n| V_n + Ct |V_t| V_t (src/RMCable/CableRMWaterLoad.h:117). Nothing to change; the local branch wip/cableelbasics-drag-on-v, which held only tests for the withdrawn ruling, is deleted.. File: resolved/MARE-0352-net-cable-drag-on-normal-velocity.md
• MARE-0355 (BUG) — NetStructure BottomContact filter advances on every port read. Resolved: 2026-10-06 (owner ruling: a first-order filter with a time constant in seconds, default 0.01 s). Net/NetStructure filters BottomContact in AcceptedStep with the new parameter BottomContactTimeConstant (0 is no filter); the port only returns the filtered value. Net/NetStructureWithConstraints and the deprecated Net/NetStructureWakeEffect never compute a contact (their port is always zero), so their per-read filter is left as is. Tests NetStructureBottomContact.ReadingThePortDoesNotChangeIt, FilterHasTheGivenTimeConstant, NegativeTimeConstantIsRejected.. File: resolved/MARE-0355-net-bottomcontact-filter-per-read.md
• MARE-0356 (BUG) — Cable/Branched OdeJacobian reads its input ports with the local state slice. Resolved: ddf9ed7, 2026-10-07 (owner instruction 2026-10-07: investigate and choose; no FhSim core change needed). Option 1: Cable/LumpedMass, Cable/Branched and Net/Disk read their input ports in OdeJacobian with the model's state vector, rebuilt from the slice with their first state index (as NetStructure); Cable/LumpedMass no longer runs its common calculation there (MARE-0359 evaluates the elements directly), and Trawl/TrawlBeam no longer runs it, as its Jacobian uses none of it. Valid wherever FhSim calls OdeJacobian: JacobianAssembler and SimObjectJacobianBlock pass state + offset of the model vector, and the checker's state-offset samples rebuild the model with the padding object first, so the object's first state index includes the padding and the vector is the padded one (all Jacobian tests pass with the shift). The trace above was wrong: the source's initial state had a sign error (G x = (0, 5.106, −10.426), which is what the probe printed); with x = (−0.4255, 0.8511, 2.5532) a BDF run (dense, SUNDIALS) of the wired input saw the right end at all 46 OdeJacobian calls at fec163f (max relative deviation 7e-15), and CheckJacobiansFromXml passes it before and after the fix: FhSim evaluates the model at the Jacobian's state first (the checker primes the ports; the assembler calls OdeFcn when it differences any column; CVODE calls f before lsetup), so the ports are cached and no result changed. Tests Cable.OdeJacobianReadsItsPortsWithTheModelState_MARE0356, CableBranched.OdeJacobianReadsItsPortsWithTheModelState_MARE0356, Disk.OdeJacobianReadsItsPortWithTheModelState_MARE0356 (the port read with the slice, red before), TrawlBeam.OdeJacobianLeavesTheCommonCalculationOfItsPorts_MARE0356 (ShipForce 201.1 instead of 0.7 after OdeJacobian, red before), and SimObject.CableBranched_JacobianWithAWiredEnd_MARE0356 (the wired input through the checker; green before and after)..

• MARE-0357 (BUG) — Cable/* advance the dynamic-stiffness mean tension at every evaluation. Resolved: ed373b1, 2026-10-07 (owner ruling: the net's pattern, R64 and MARE-0224). Cable/LumpedMass and Cable/Branched advance the mean tension in PreOdeFcn (new InternalCable::AdvanceMeanTension), once per new time, from the step's start state after applying the Length inputs at it; OdeFcn and the port calculations only read it. CableElDynStiff::UpdateLength no longer advances it and the per-call stopwatch is gone. The stiffness factor takes the unblended water density (m_rhoWaterFull), so it depends on the element length alone. Cable/LumpedMass's OdeFcn applies its Length input at its own (T, X), as Cable/Branched does since MARE-0037. Tests Cable.OdeFcnDoesNotDependOnPortReadsWithinTheStep_MARE0357 and Cable.PreOdeFcnAdvancesTheMeanTensionOncePerStep_MARE0357, red before (the derivatives after three port reads at other times and states differed from those without; a second step did not change the mean tension, as PreOdeFcn did nothing), green after..

• MARE-0358 (BUG) — The dynamic-stiffness mean tension moves away from the real tension. Resolved: 7b317e4, 2026-10-07 (owner ruling 2026-10-07: alternative B, replacing option A of 316d8bd). The mean tension is a first-order filter towards the element's own tension, T = eps · eFactor · EA + (1 − eFactor) · m (bounded to [0, MaxTension]; the difference bounded at a tenth of MaxTension, as before), with the time constant AdaptationPeriod, m += (1 − exp(−Δt/AdaptationPeriod)) · (T − m), exact for a tension constant over the step, starting at MeanTension; a step of zero leaves it. The PID controller is gone. Under a constant load the mean tension reaches the load with the time constant AdaptationPeriod and the strain becomes load / EA. Option A (target strain · EA, 316d8bd) has the same end state but under a load the time constant eFactor · AdaptationPeriod (1.8 ms for FhSim_trawlwriter's bridles) and overshoots: the middle bridle of Alfredo5_2 peaked at 100 kN, the MaxTension/10 bound. Tests CableElDynStiff.MeanTensionStartsAtItsSetting_MARE0358 (red before both: 0 instead of 5000) and CableElDynStiff.MeanTensionReachesAConstantLoadWithTheAdaptationPeriod_MARE0358 (end B a massless node in equilibrium with 1000 N, AdaptationPeriod 2 s, steps of 0.01 s: 632.1 N after one period, the load after ten; red with option A: 1000 N after one period). No baseline of this library, fhsim_fishery or FhSim_trawlwriter compares a result with AdaptationPeriod ≠ 0; the effect on the trawlwriter systems (bridles with 0.1 s) is in the workspace's FEATURE.md..

• MARE-0359 (BUG) — InternalCable's Jacobian takes the masses of the last evaluation and leaves out the mean tension. Resolved: 6887a93, 2026-10-07. Cable::OdeJacobian and CableBranched::OdeJacobian evaluate the elements at their own state first (InternalCable::EvaluateElementsAt; Cable/Branched also applies its Length inputs and PrepareSections there and sums its junction inertias from InternalCable::EndInertia); the Jacobian's tension is eps · eFactor · EA + (1 − eFactor) · meanTension, signed, as in AddStructuralForces, with no derivative of the mean tension (held through the step). The four tests below are green; the Jacobian checks of Cable/LumpedMass, Cable/Branched, Net/Disk and Trawl/TrawlBeam pass at their tolerances, and a BDF run of the wired Cable/Branched input ends normally and agrees with a tight RK45 run at 0.05 s to 5e-5 relative in the positions and 0.2 % in the velocities..

• MARE-0361 (BUG) — A panel whose aft and front edges are both under 20 meshes meshes into two-node elements. Resolved: c03d0e0, 2026-10-08. Fix 1 (owner ruling 2026-10-08, option A): ReadNetSpec refuses a panel of only one section, codend included, whose end edges are both under m_dMinNodeSeparation = 20 meshes (T1 and T2 times MeshCountFactor), naming the file and line of the section. That is exactly the case of two-node elements: a belly element loses its front side node only on the panel's front section and its back side node only on section 0 (CTrawlNetAssembler.cpp:1209-1227), splitter and wing elements always keep at least three. A splitter with no wing section in front, which read past the wing nodes (PanelNodes_PRTWING[0] of an empty vector) and crashed, is refused too (MARE-0362). Tests TrawlNetSpecReader.OneSectionPanel_BothEndEdgesUnder20Meshes_IsRefused_MARE0361 and ..._EdgesUnder20MeshesAfterMeshCountFactor_IsRefused_MARE0361 (red at 09bc894, green), ..._OneEndEdgeOf20Meshes_MeshesIntoTriangles_MARE0361 and TrawlNetSpecReader.TwoSectionPanel_NarrowEndEdges_MeshesIntoTriangles_MARE0361 (accepted, elements of three nodes).

• MARE-0363 (BUG) — A splitter as a panel's aft section with an aft edge under 20 meshes gives elements with one node twice. Resolved: a50950d, 2026-10-08. Fix 1 (owner ruling 2026-10-08): ReadNetSpec (CheckMeshable) refuses a panel whose section 0 is the splitter with T2 (times MeshCountFactor) under m_dMinNodeSeparation = 20 meshes, naming the file and line of the section. That is exactly the case of a repeated node: HasTriangularAft joins the first side nodes to the centre node (CTrawlNetAssembler.cpp:195-198), and only the splitter elements (:1238-1290) take the aft side nodes without a check; a belly section 0 drops them (bIsAftTriangle), and wing sections are never section 0. Tests TrawlNetSpecReader.AftSplitterWithNarrowAftEdge_IsRefused_MARE0363 (red at f232ad2, green) and TrawlNetSpecReader.AftSplitterWithAftEdgeOf20Meshes_MeshesWithoutARepeatedNode_MARE0363 (accepted, no element with a repeated node)..
