Solvers

The solvers.quasistatic.QSSolver class provides a refactored solver that includes automatic Type 1, Type 3 and collision detection solving after each function evaluation. Use it with:

solver = QSSolver(with_t1=True, with_t3=True, with_t3=True)
solver.find_energy_min(sheet, **minimize_kwargs)

The function signature is a bit different from the previous sheet_vertex_solver.Solver as key-word arguments are directly passed to scipy minimize function. You thus need to replace:

solver_kw = {'minimize': {'method': 'L-BFGS-B',
                          'options': {'ftol': 1e-8,
                                      'gtol': 1e-8}}}
solver.find_energy_min(sheet, **solver_kw)

by:

solver_kw = {'method': 'L-BFGS-B',
             'options': {'ftol': 1e-8,
                         'gtol': 1e-8}}}
solver.find_energy_min(sheet, **solver_kw)

to use the new solver.
Note that sheet_vertex_solver.Solver is still available.

Behavior

Event management refactoring

We refactored event management with a keyword arguments only design to make passing complex parameter dictionnaries easier.

Actions and events where added for monolayer objects.

There is now an option in the manager append methods kwargs to add unique event or not.

Licence

We switched to GPL to be able to use CGAL without worrying. If this is
a problem to you, we can offer accomodations.

Vizualisation

The use of the top level draw.sheet_view function is encouraged. It is now possible to specify visibility at the single face level with a "visible" column in the face DataFrame.

Core

  • Added a History class to handle time series of sheet movements

Geometry

  • Lumen volume calculation on a new geometry class (#110)
  • Create a new segment vertex category : lateral in Monolayer
  • adds finally statement to scale_unscale utils
  • Change 'sagittal' key word by 'lateral' key word

Dynamics

New quasitatic solver class.

New effectors

  • Add LumenVolumeElasticity effector
  • added SurfaceTension effector

Bug fixes

  • reset catched ValueError to Exception waiting for pandas to publish 0.24
  • Better opposite management and validation for Sheet, closes #72
  • Correction of color face (#85)
  • fixes reset_specs warning formatting bug
  • Correction of segment category for new faces create in IH transition

Misc

The codebase now uses black to format all the code base.

Pruning

  • removed old isotropic model
  • removes multisheet (#105)
