Documentation

Release 2.2.0b [2016-02-11]

Enhancements:

  • Improved function evaluation efficiency.
  • Handle numpy int types in index sets correctly.
  • Webgl figure saving.
  • General visualisation enhancements.
  • Better testing for visualisation.
  • petsc 3.7 compatibility

New Features:

  • ParticleFound function. Allows for 'sparse' swarm operations.
  • Figure copying functionality
  • SurfaceOnMesh visualisation object

Documentation:

  • HTML api documentation.
  • Big docstring updates.

Deprecated:

  • 'swarm' parameter now removed in favour of 'voronoi_swarm' parameter.

Release 2.1.2b [2016-10-31]

  • Bug fix for the stokes system's psuedo incompressibility

Release 2.1.1b [2016-10-13]

  • Improvements for docker usage.

Release 2.1.0b [2016-10-11]

New Features:

  • Shadow particles sync added.
  • Finer solver execution control.
  • Added XOR function.
  • Can now describe functions using python tuples: fn = (fn1, fn2, fn3)
  • Inline interactive visualisation.
  • Better handling of systems without rendering capabilities.
  • gLucufer Surface renderer resolution setting.
  • Parallel and recursive test runner.

Bug Fixes:

  • General improvements to stability and error handling.
  • MeshVariables can not be used with multiple SLE systems.
  • glucifer deadlock when deleting from db in parallel.
  • glucifer DB situation where zero compression results in abort().
  • glucifer valueRange fix.
  • Fn.MinMax parallel fix.
  • Issue saving swarms in parallel.

Documentation:

  • Big update for User Guide.
  • New examples added.
  • Examples updated for better usage patterns.
  • Updates for docstrings & doctests.
  • New & updated build recipes.

Interface changes:

  • SLE 'swarm' option renamed to 'voronoi_swarm'
  • Conditions can be passed in directly now instead of in lists.

Release 2.0.3b2 [2016-06-08]

  • Pseudo Compressibility python wrapped.
  • Neumann boundary conditions for Stokes & SSHeat & AdvectionDiffusion (SUPG!)
  • Exposed population control mechanisms. Zero population control now occurs without using the uw.swarm.PopulationControl object.
  • Bug: Potentially critical bug in the integration to material swarm mapping fixed.
  • Glucifer/LavaVu graphics 'Store' workflows introduced.
  • Dockers upgraded to use ipyparallel where possible.
  • Global evaluation for functions (experimental!)
  • Exposed non-linear tolerance.
  • Deprecated various old interface options.
  • PICIntegrationSwarm -> VoronoiIntegrationSwarm
  • Viscoelasticity implementation and example.
  • 'deform_swarm' context manager for particle relocations.
  • Auto-repopulate now occurs for voronoi swarms (except for the uw.utils.Integral class)
  • SUPG source terms.
  • MeshVariable_Projection method introduced.
  • Various bug fixes.
  • Various documentation improvements.
  • Various testing improvements.
  • Various other minor impementations.
