v2.12.0.dev0

What's Changed

Added

• Added CornerFinderSpec.corner_rounding_collapse_extent so LayerRefinementSpec can recover sharp corners that pass the legacy angle threshold from small rounded or chamfered imported geometry.
• Added ImpedanceSpec to support complex-valued LumpedPort impedance. The impedance field now accepts either a plain real number (e.g. 50) or an ImpedanceSpec(impedance=..., frequency=...) for complex-valued loads. A complex impedance Z = R + jX is mapped to a series RL or RC load at the given measurement frequency, enabling reactive terminations in S-parameter simulations. Purely reactive loads (Re(Z) = 0) are not supported; Re(Z) must be strictly positive to ensure a stable FDTD pole.
• Added a dedicated PyTorch wrapper plugin documentation page under api/plugins/pytorch.
• Added autograd support for ClipOperation geometry derivatives, including union, difference, intersection, and symmetric_difference.
• Added the tidy3d mcp command for running the Tidy3D MCP server from the active Tidy3D environment.
• Added Palik_NoLoss material-fitter refits for the low-loss Palik ranges of GaAs, Ge, SiO2, and cSi, and Palik_LowLoss variants for the previous Palik fits of GaAs, Ge, InP, SiO2, and cSi.
• Added per-interface physical residual diagnostics for EME: incident-normalized squared tangential E/H field residuals, corresponding non-PML-aperture residuals, and the flux-weighted power conservation defect, stored on EMESimulationData.diagnostics when EMESimulation.eme_diagnostics=True.
• Added a progress keyword (default True) to EMESimulation.compute_overlaps, EMESimulation.propagate_from_overlaps, and EMESimulation.propagate that shows a per-phase rich progress bar on the logging console; pass progress=False to silence it.
• Accelerated charge solver support for the Masetti mobility model.
• DeviceCharacteristics.dc_convergence (new SteadyConvergenceData) flags per-bias Newton convergence and exposes the per-iteration residual trace, so callers can mask the I-V/C-V curves by the converged biases and inspect at which iteration each bias crossed the tolerance.
• Added support for explicit payment type, priority, and vGPU allocation settings when submitting component modeler batch tasks.

Changed

• WavePort and TerminalWavePort mesh refinement now interprets num_grid_cells as the cell count along the largest transverse dimension (the smaller dimension is aspect-ratio-scaled), with the default raised from 5 to 12. Two grid-snapping points are also emitted at opposite corners of the port plane.
• Changed the default autograd minimum_spacing_fraction from 0.01 to 0.001; set it back to 0.01 in your config to keep previous spacing behavior.
• UniformUnstructuredGrid.min_edges_per_circumference and min_edges_per_side now accept 0, which skips the corresponding local mesh-size contribution. A deprecation warning is emitted when either field is left at its default: the default will change to 0 in the next release. Set the fields explicitly to preserve the current behavior.
• Changed grid validation to raise a units error when UniformGrid.dl or generated AutoGrid / QuasiUniformGrid cell sizes are below 1e-6 um.
• Improved memory usage and runtime for autograd local far-field projections in the 3D paired approximate path used by Cartesian and k-space monitors with far_field_approx=True.
• Reduced peak memory usage when differentiating exact local field projections (far_field_approx=False).
• Increased default ChargeToleranceSpec.max_iters from 30 to 120; set it explicitly to keep the previous behavior.
• HeatChargeSimulation.use_accelerated_solver=False (selecting the CPU charge solver) is now validated at construction and raises a ValidationError on use_accelerated_solver for configurations the CPU solver cannot run: heat and conduction simulations (which always run on the GPU accelerated solver) and charge simulations using GPU-accelerated-only features such as MasettiMobility or SSAC at_voltages bias-point selection. The flag now defaults to True (was Optional defaulting to None) and continues to use the GPU accelerated charge solver.

Fixed

• Suppressed the Simulation structure-at-boundary warning for structures touching Periodic or BlochBoundary edges, while keeping the warning for other boundary types unless structure extrusion is enabled.
• Improved auto-generated API documentation for classes with computed default values (e.g. NedeljkovicSorefMashanovich), eliminating malformed Parameters sections and a long tail of other documentation build issues.
• Raise a validation error when an automatically added PEC frame (around a mode source with PECFrame or an internal absorber) overlaps the absorbing-boundary extrusion clipping region on any boundary with extrude_structures=True. To opt out on a side that legitimately needs the source / absorber to reach the boundary (e.g. a wave-port source that spans the lateral domain via symmetry), pass extrude_structures=False to the boundary — either through Boundary.pml / Boundary.stable_pml / Boundary.absorber (now exposed there) or by constructing Boundary(plus=td.PML(extrude_structures=False), minus=td.PML(extrude_structures=False)) explicitly.
• TerminalComponentModeler.ports and ModalComponentModeler.ports now use a discriminated union on the type field, so validation errors for a port dict are attributed to the correct port class instead of being scattered across every union branch.
• Fixed PolySlabSet to preserve its internal ring order across safe_update() and other vertex-space updates while still exporting area-sorted structures.
• Fixed mode solver picking the wrong sqrt root for lossless evanescent modes; direction is now resolved from time-averaged power flow with a passivity fallback.
• Fixed device characteristic DataArrays to expose value units and voltage coordinate units when simulation data is loaded.
• Fixed EMESimulation.plot_3d() to clip infinite structures to the simulation bounds.
• EME interface matching now uses the full solved modal basis as test rows, except modes with numerically unusable self-overlap, so high mode counts no longer slowly degrade S-matrix accuracy. Only the propagation trial basis is capped by EMEModeSweep.num_modes or EMEModeSpec.sort_spec.keep_modes; modes flagged increasing (Im(n_eff) < -EMEModeSpec.increasing_mode_tolerance) remain available as test rows. The default increasing-mode tolerance now ignores roundoff-level negative imaginary effective indices in lossless cases. The per-cell EMEModeSpec.num_modes cap is raised from 100 to 1000 for convergence studies; practical mode counts remain limited by interface memory and dense interface/stacking runtime.
• Fixed edge singularity correction for geometry groups and difference boolean operations in conformal meshing.
• Fixed RF/modeler diverged runs to report a clear task status error instead of trying to download missing aggregate data.

Removed

• Removed deprecated Scene.plot_heat_conductivity(), Scene.plot_structures_heat_conductivity(), and Scene.heat_conductivity_bounds(); use plot_heat_charge_property(property="heat_conductivity"), plot_structures_heat_charge_property(property="heat_conductivity"), and heat_charge_property_bounds(property="heat_conductivity").
• Removed deprecated AbstractSimulation.plot_structures_heat_conductivity() and HeatChargeSimulation.plot_heat_conductivity(); use scene.plot_structures_heat_charge_property(property="heat_conductivity") and plot_property(property="heat_conductivity").
• Removed the deprecated legacy config API and legacy config migration paths.
• Removed TopologyDesignRegion.params_uniform(), params_random, params_zeros, params_half, params_ones, AbstractOptimizer.initialize_result(params0), and AbstractOptimizer.run(..., params0=...). For direct parameter arrays, replace the TopologyDesignRegion.params_* helpers with NumPy arrays using region.params_shape, such as np.full(region.params_shape, value), np.random.random(region.params_shape), np.zeros(region.params_shape), 0.5 * np.ones(region.params_shape), or np.ones(region.params_shape). For optimizer starting parameters previously passed as params0, configure the design region before constructing or updating the enclosing design and optimizer; use CustomInitializationSpec(params=params0) to preserve an existing array, or RandomInitializationSpec(seed=...) for reproducible random starts.
• Removed deprecated SimulationData.plot_field(field_name="int"), SimulationData.plot_field(..., freq=...), and SimulationData.plot_field(..., time=...); use field_name="E", val="abs^2", plot_field(..., f=...), and plot_field(..., t=...).
• Removed deprecated to_field_monitors() method on terminal-based scattering-matrix ports (e.g. LumpedPort, WavePort); use to_monitors() instead.

Planned Deprecation

• Palik_Lossless is deprecated as a material-library variant name; material-library lookup now warns and returns Palik_LowLoss, while Palik_NoLoss provides zero-loss Palik fits where supported by low-loss source ranges.

Full Changelog: v2.11.2...v2.12.0.dev0

v2.11.2

What's Changed

Added

• Added documentation page explaining the three S-parameter definitions (pseudo, power, symmetric_pseudo) in TerminalComponentModeler, including mathematical derivations, symmetry properties, and power calculations.
• TerminalComponentModeler now warns when its freqs exceeds the soft limit used by frequency-domain monitors.
• Added local EME support for expressing a propagated S-matrix in user-supplied port modes.

Changed

• Added Result.real_cost to the design plugin so pre/post runs can report billed FlexCredit usage after execution.
• Increased the maximum number of EME cells from 100 to 500.

Fixed

• Fixed mode solver to place PEC boundaries at the closest grid boundary outside the monitor plane, matching user expectations when using the plane bounds as PEC locations (common in RF workflows). Added solver_field_bounds to ensure accurate field interpolation near the hard boundary.
• Fixed eps_model() across Tidy3D media classes to consistently accept scalar, list, and NumPy array frequency inputs, including custom and anisotropic media.
• Fixed ModeSimulation.from_mode_solver() to infer a wavelength from the mode-solver-associated simulation source when converting simulations that use auto grid without an explicit grid_spec.wavelength.
• Fixed TFSF source validation to reject setups whose in-domain region collapses to zero extent along both tangential directions, such as 1D simulations.
• Fixed CustomPoleResidue adjoint postprocessing to preserve the frequency axis for zero-gradient multi-frequency chunks.
• Stabilized Tidy3D model JSON float formatting across supported pydantic-core versions.
• Fixed EME S-matrix basis conversion for EMEModeSweep results that request different numbers of modes at different sweep points.
• Fixed TerminalComponentModeler to snap WavePort internal absorbers and mode sources to the updated simulation grid (which includes the wavelength override and mesh overrides) rather than the original user-provided grid, preventing absorbers from landing off-grid in the final simulation.
• Fixed inline PyVista plots in Jupyter on Python 3.13+ so they render interactively instead of failing or falling back to a static image.

Full Changelog: v2.11.1...v2.11.2

v2.11.1

What's Changed

• Added local EME propagation via EMESimulation.propagate(mode_data) and a per-element staged pipeline (mode_simulations, stage_cell_modes, compute_cell_overlap, compute_interface_overlap, compute_cell_smatrix, compute_interface_smatrix, compute_smatrix). For iterative design with many sweeps on the same modal basis, compute_overlaps(mode_data) + propagate_from_overlaps(cell_overlaps, interface_overlaps) amortizes the overlap stage. Intermediate results (EMEStageCellOverlap, EMEStageInterfaceSMatrix, etc.) are serializable and reusable across parameter sweeps. EMEFreqSweep is not supported; use EMESimulation.freqs directly. The local path does not support anisotropic media in bent cells with bend_medium_frame="global"; use bend_medium_frame="co_rotating" or the remote backend in that case. by @caseyflex
• Added filter_func support to MethodGrid and MethodMonteCarlo in the design plugin so invalid parameter combinations can now be skipped during parameter sweeps. by @marcorudolphflex
• Added plot_field_components() to ModeSimulationData and ModeSolver for plotting multiple mode field components in one call. by @marcorudolphflex
• Added FieldProjector.from_near_field_data() for projecting directly from custom or modified FieldData. by @marcorudolphflex
• Improved near-field projection performance. by @marcorudolphflex
• Strip autograd tracers from DataArray plotting functions before plotting. by @groberts-flex
• Keep original simulation data from being zeroed out during the adjoint pipeline. by @groberts-flex
• Updated adjoint shape integration to sample interface permittivity directly from anisotropic simulation permittivity data. by @groberts-flex
• Fixed ValueError shape mismatch in Simulation.epsilon() when a CustomMedium uses ScalarFieldDataArray with a frequency dimension, by squeezing the leftover f dimension after spatial interpolation in eps_diagonal_on_grid. by @daquinteroflex
• Fixed wrapped angle_theta handling for glancing-incidence checks so values like -pi/2 and 5*pi/2 are validated consistently in ModeSpec and angled field sources. by @momchil-flex
• Added frontend validation for TCAD refinement regions and lines so unsupported degenerate shapes are rejected before submission. by @momchil-flex
• Fixed plot function override for tidy3d data arrays. by @groberts-flex
