v0.4.0

TrixiParticles 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.

v0.3.0

Diff since v0.2.7

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).
