Issues

• Exec/run2d/test_grids: all eleven shipped inputs_* decks abort at startup (no prob.probtype, unread probin files, RZ with viscosity)

• Diffusion: diffuse_Ssync, FillBoundary, viscFluxReg, maxOrder, tensorMaxOrder and the computeAlpha alpha_in path are never exercised

  AMReX-Fluids/IAMR#241 · Filter by author WeiqunZhang opened on Oct 7, 2026
  

• Diffusion::diffuse_scalar: with rho_flag==1 and delta_rhs, the old-time diffusion term is also multiplied by rho_half

• MacProj::mac_sync_compute (known-edge-state overload) and OutFlowBC::SemiGrow/SemiCoarsen have no callers

• Projection.H: filterP is declared but never defined; set_outflow_bcs ignores Vel_in/Divu_in, so its have_divu gating and the divu comments are stale, and nodal_proj.add_vort_proj only feeds unreachable code

• NS_init_eb2.cpp: init_eb/initialize_eb2_structs/define_body_state/set_body_state are never called, and would touch device-resident EB flags from the host if revived

  AMReX-Fluids/IAMR#233 · Filter by author WeiqunZhang opened on Oct 7, 2026
  

• Initialize_bcs: an old-style ns.lo_bc/hi_bc entry silently overrides a conflicting xlo.type, defeating the "Multiple conflicting BCs" check

• Utilities.cpp: read_binary/read_csv are unused, write past the caller's vector, and read_binary does not match its declaration under USE_FLOAT

  AMReX-Fluids/IAMR#227 · Filter by author WeiqunZhang opened on Oct 7, 2026

• ComputeAofs: non-EB flux-register path ignores do_crse_add/do_fine_add, so the mac_sync adds coarse fluxes the EB twin skips

• velocity_update / scalar_update: a NaN in the new state ends the run with exit(0), reporting success

• main(): a run that sets only stop_interval aborts before stop_time is derived from it

• Diffusion::getViscTerms: on level>0, Laplacian_SoverRho scalars call crse_ns.get_rho(time) at a fine-substep time, which dereferences a null rho_qtime for ref ratio 4

• computeRhoG: with EB, the hydrostatic outflow strip integrates the covered-cell sentinel density (1.2345e20 / 1e40), poisoning the Dirichlet pressure on every fluid node below a covered cell

• reflux: with EB, the viscous reflux divides the cut-cell correction by the full cell volume instead of vfrac*volume

• NavierStokesBase::calc_mut_LES: the Smagorinsky/Sigma eddy viscosity is kinematic (nu_t) but is added to the dynamic viscosity mu

• reflux: the viscous reflux of a non-conservative Laplacian_S tracer is divided by rho_half, although its diffusion equation carries no density
