Change log {#changelog}

Changes in progress

version 1.0.0

  • Inclusion of only-on-GPU operation of voronoi models.
  • openMP for cpu multithreaded operation
  • Switch to cmake build system -- see installation.md for details
  • Update cgal to use header-only versions
  • Retire the use of Dscalars... switching at compile time was never used, so now everything is a double
  • (almost) all API remains the same -- "deprecated.h" was finally removed, so if you used very old class names you'll have to update them, but otherwise your code should work fine. BoxPtr has been changed to PeriodicBoxPtr, though.

version 0.8.1

  • Assorted bug fixes and clean-ups

version 0.8.0

  • A directory to put common MD data analysis tools has been added
  • Changed strategy for handling multiple T1 transitions per cell / vertex
  • Numerous small changes

version 0.7.1

  • Support for non-square boxes... DelaunayCGAL calls currently implemented, but not DelaunayLoc
  • Nose-Hoover thermostat-chain NVT simulations
  • Starting transition away from Simple2DActiveCell class by using velocity GPUArrays in SPP updater

version 0.7

  • Cell death added. This removes a cell in Voronoi model, or does a T2 transition in vertex model
  • PeriodicBoxPtrs implemented...will eventually make different box shapes easier
  • rationalize naming scheme of vertex and voronoi models
    • There are now vertexModelBase and voronoiModelBase classes
    • Derived classes of these largely just need to implement force laws
  • include tree cleaning

version 0.6.2

  • Implement cell division in both vertex and Voronoi models
  • Major bug fix in "quadratic" vertex model force computations

version 0.6.1

  • system-wide refactoring into simulation components: updaters, configurations, pieces, and a Simulation to tie them together
  • added simple Brownian dynamics equation of motion
  • added a (somewhat specialized) calculation of the quadratic voronoi model dynamical matrix

version 0.6

  • started refactoring class structures... beginning with equations of motion

version 0.5.1

  • added FIRE minimization algorithm
  • Simplified interface to SPV2D and AVM2D; have all models implement virtual functions to provide a common interface for MD

version 0.5

  • First major restructuring of class structure...

cellGPU version 0.4

  • The AVM2D class implements a simple active vertex model
  • numerous bug fixes
  • GPU optimizations

version 0.3

  • SPV2D class inherits from DelaunayMD; implements the 2D self-propelled voronoi model
  • references to Triangle are removed; CGAL becomes the default triangulation library

DelGPU version 0.2

  • "DelGPU" implements the DelaunayCheck class to assess the validity of a proposed triangulation on either the CPU or GPU; DelaunayMD provides a simple interface to an MD-like protocol

VoroGuppy version 0.1

  • "VoroGuppy" has a CPU implementation of Chen and Gotsman's localized Delaunay triangulation, comparisons with Shewchuck's Triangle program and a Bowyer-Watson implementation.
