0070 — FhSimUI segfaults after it reports a failed render system initialisation

0119 — A stop request is not polled for a step that produced no data

0147 — The NetworkRoundTrip tests bind fixed TCP ports and collide when two runs overlap

0148 — -o is ignored without a word for a Replay or Network provider without OBSERVERS

0072 — A Debug build with visualization leaves about 148 GB of test FMUs in its build folder

0073 — The v3 migration guide and the tutorial pages miss what porting fhsim_tutorial and fhsim_maritime needed

0074 — RK45_i gains energy in an under-resolved contact where v2 did not

0108 — A licence file cut by more than the writer's header padding loses its last entry without an error

0113 — An empty `` is exported as a Real parameter with no values

0115 — The FMU exporter reads `Size_<port>` with `std::stoi`, so `Size_y="2x"` reads 2

0167 — An FMU does not tell the master that a model asked to stop

0152 — AcceptedStep and the diagnostics read the last solver iterate under SUNDIALS

0174 — BackwardEuler_i has no switch to a numeric Jacobian

0175 — The self-connection check misses other users of the model Jacobian

Module fhsim_coribo

0012 — ConstraintSolver warm-starts a 5-iteration CG from the previous call, so OdeFcn is not idempotent

0023 — CollisionManager::AddPlate passes the full thickness as the plate radius, addExternalPlate half of it

0024 — ConstraintSolver(double, CoreBoundThreadPool*) takes ownership through a raw pointer

Module fhsim_fishery
0120 — Sample clocks and controllers start at 0 whatever TStart is
Module fhsim_marine_elements

0428 — The library builds with 211 warnings under -Wall -Wextra

0430 — Remaining stdout diagnostics of the net force kernel and the net spec

Module marine_elements_RigidBarCable
0429 — Cable/RigidBarCable ports return the buffers of the last OdeFcn, not the values at the state they are read at

Page Usage
0130 — NetCDF variables are read in the order (time, zc, yc, xc) without checking it Known review issues are listed in Review issues — fhsim_environment. Test coverage and Jacobian verification are summarised in Testing report. Wakes, how to place one and who sees them, are summarised in Wakes; every wake parameter (CastWake, Wake*, ExternalWakeUpdate) is listed once in Wake parameters. The laws by which the water loads a body (net panels, spheres, discs, cable elements) and its submerged fraction are in Hydrodynamics: shape and panel load laws; the panel load laws are validated against measurements in Panel load laws: validation report.
