Breaking Changes

• Clipping of negative pressure values in the BoundaryModelDummyParticles is now disabled
  by default and can be enabled with the keyword argument clip_negative_pressure=true (#1143).
• The example files are now loading sub-packages of OrdinaryDiffEq.jl instead of
  OrdinaryDiffEq.jl itself. For example, using OrdinaryDiffEqLowStorageRK instead of
  using OrdinaryDiffEq (#1154).
• DensityDiffusionAntuono now only has the kwarg delta and no positional
  arguments (#1142).
• Return type of vtk2trixi changed to NamedTuple including an optional
  :initial_condition field if create_initial_condition=true is passed (#959).
• Public system constructors now use keyword arguments for configuration values.
  This affects WeaklyCompressibleSPHSystem, EntropicallyDampedSPHSystem,
  ImplicitIncompressibleSPHSystem, TotalLagrangianSPHSystem, DEMSystem,
  and BoundaryDEMSystem.

Migration Guide for Keyword-Based System Constructors

The initial condition remains the only positional argument for the affected system
constructors. All method, material, and configuration arguments that were previously
passed positionally now need to be passed as keywords.
Existing optional keyword arguments remain available. For example, the
density_calculator keyword of EntropicallyDampedSPHSystem still defaults to
SummationDensity().

Here are examples, where ic is the initial condition, kernel is the
smoothing kernel, and h is the smoothing length:

WeaklyCompressibleSPHSystem(ic, density_calculator, state_equation, kernel, h;
                            kwargs...)
# becomes
WeaklyCompressibleSPHSystem(ic; smoothing_kernel=kernel, smoothing_length=h,
                            density_calculator, state_equation, kwargs...)

EntropicallyDampedSPHSystem(ic, kernel, h, sound_speed; kwargs...)
# becomes
EntropicallyDampedSPHSystem(ic; smoothing_kernel=kernel, smoothing_length=h,
                            sound_speed, kwargs...)

ImplicitIncompressibleSPHSystem(ic, kernel, h, reference_density; kwargs...)
# becomes
ImplicitIncompressibleSPHSystem(ic; smoothing_kernel=kernel, smoothing_length=h,
                                reference_density, kwargs...)

TotalLagrangianSPHSystem(ic, kernel, h, young_modulus, poisson_ratio; kwargs...)
# becomes
TotalLagrangianSPHSystem(ic; smoothing_kernel=kernel, smoothing_length=h,
                         young_modulus, poisson_ratio, kwargs...)

DEMSystem(ic, contact_model; kwargs...)
# becomes
DEMSystem(ic; contact_model, kwargs...)

BoundaryDEMSystem(ic, normal_stiffness)
# becomes
BoundaryDEMSystem(ic; normal_stiffness)

Performance

• Greatly improved GPU performance of WCSPH and TLSPH
  (#1128, #1117, #1124, #1125, #1130, #1116, #1139, #1149).
  See #1131
  for a detailed breakdown including benchmark results.

Features

• Added a SortingCallback that can be used to sort particles by their spatial location
  to improve performance (#1044).

Important Bugfixes

• Fixed a bug where DensityDiffusionAntuono could not be used together with open
  boundaries and BoundaryModelDynamicalPressureZhang (#1043).
• Fixed a bug where no-slip boundary conditions were not applied correctly when not using
  ViscosityAdami (#1089).

v0.4.0

Diff since v0.3.2

Breaking changes

• Renamed BoundarySPHSystem to WallBoundarySystem and the keyword argument
  movement to prescribed_motion.

• Renamed OpenBoundarySPHSystem to OpenBoundarySystem.

• Renamed BoundaryMovement to PrescribedMotion. The movement_function must now be
  a function of (x, t) returning the new position instead of an offset.
  For example, movement_function(t) = SVector(t, 0.0) now needs to be
  movement_function(x, t) = x + SVector(t, 0.0).

• Renamed directory solid to structure in the examples file tree.
  VTK files for the TotalLagrangianSPHSystem are now also called structure_*.

• Renamed keyword argument n_fixed_particles of the TotalLagrangianSPHSystem
  to n_clamped_particles.

• API for OpenBoundarySystem and BoundaryZone changed.
  It is now possible to pass multiple BoundaryZones to a single OpenBoundarySystem.
  Reference values are now assigned individually to each BoundaryZone. (#866)

• Rename keyword arguments plane and plane_normal for BoundaryZone to boundary_face and face_normal (#597).

• The argument of TransportVelocityAdami is now a keyword argument.
  TransportVelocityAdami(1000.0) now becomes
  TransportVelocityAdami(background_pressure=1000.0) (#884).

• Combined transport velocity formulation (TVF) and particle shifting technique (PST) into
  one unified framework.
  The keyword argument transport_velocity now changed to shifting_technique.
  The ParticleShiftingCallback has been removed. To use PST, use the UpdateCallback
  instead, and pass shifting_technique=ParticleShiftingTechniqueSun2017() to the system (#884).

• Renamed the keyword argument tlsph to place_on_shell for ParticlePackingSystem,
  sample_boundary, extrude_geometry, RectangularShape, and SphereShape (#814).

• Custom quantity functions passed to SolutionSavingCallback or PostprocessCallback
  that were not using the documented API but were functions of
  (system, v_ode, u_ode, semi, t) now need to be functions
  of (system, dv_ode, du_ode, v_ode, u_ode, semi, t) (#879).

• Renamed each_moving_particle to each_integrated_particle,
  n_moving_particles to n_integrated_particles
  and active_particles to each_active_particle.

Breaking Changes

• Rescaled the Wendland kernels by a factor of 2 to be consistent with literature.
  This requires adjusting the previously used smoothing length for the Wendland Kernels
  by dividing them by 2 as well to obtain the same results (#775).

• The API for custom quantities and functions in the PostprocessCallback changed (#755).

• The API for choosing parallelization backends changed. The keyword argument data_type
  in semidiscretize was removed and a keyword argument parallelization_backend was added
  to Semidiscretization. See the docs on GPU support for more details.

• The API for the DEMSystem changed (#756).
