  • May 1st, 2007: Continuity 6.3 revision 3127 was released. Highlights include:

    • Massive memory leak fixed in electrophysiology
    • Fixed bug in material law with transversely isotropic exponential function of Lagrangian strains
    • Element labels can now use regular expressions in the list volume form.
  • April 26th, 2007: Continuity 6.3 revision 3099 was released. Highlights include:

    • Cont6 files (pickle files) are now compressed and decompressed when saved and loaded.
    • All data sent to and from remote server is compressed resulting in a 3X speed up in client/server communications.
    • Added 40 new unit test cases.
    • Fixed old event/threading leak where a new event is propagated during the creating of each new quad surface. This fixes limitation where only 30 surfaces could be rendered.
    • Added the ability to have up to 10 user defined commands in the options menu.
    • Systematically tested all example scripts in example directories for reliability.
    • Added ability to render contours (isolines) to OpenMesh quads by implementing a marching squares algorithm.

    • Many improvements for the electrophysiology equation editor.
    • Optionally automatically update the biomechanics initial conditions during nodal refinement.
    • Force boundary conditions are working again, and list boundary conditions properly lists them (as natural bcs)
    • Solving algorithm updated to allow use of an ODE-based active stress model.
    • Modified the refine form to allow user to input customize xi’s during refinement.
  • February 23th, 2007: Continuity 6.3 revision 2880 was released. Highlights include:

    • Critical bug fix with building boundary conditions from scratch
    • Various bug fixes and code optimizations
  • February 14th, 2007: Mark your calendar: Continuity Summer School scheduled to July 30th to August 3rd, 2007

  • February 13th, 2007: Continuity 6.3 revision 2853 was released. Highlights include:

    • Critical bug fixes with Mac/Linux builds
    • Fixed problems with volume calculations.
    • Equations editor improvements
    • Improved list nodal solutions and list boundary conditions
    • Added more useful error messages with threads/no threads client/server conflicts.
  • 2007 RAC PowerPoint, LQT3 movie

  • 2006 Continuity Report

  • January 26th, 2007: Continuity 6.3 revision 2755 was released. Highlights include:

    • Enigmatic “pickle” files have been replaced with more intuitively named “cont6” files. All problem data will now be saved and read using this convension.
    • Major bug fix for selective refinement for 2D (and 1D) problems.
    • Updated comments for all the variables for Beeler Reuter model.
    • Added Fitz-Hugh Nagumo electrophysiology model.
    • Refactored parallel electrophysiology to use same mpi system as biomechanics. This allows “cell models” definited using the equations editor to automatically work in parallel.
  • January 8th, 2007: Continuity 6.3 revision 2684 was released. Highlights include:

    • Parallelized biomechanics nonlinear solver to work on a cluster. Some problems show a 10X speed up when solved in parallel.
    • Implemented elastica materials for biomechanics
    • For Windows, continuity server capable of using a web service to dynamically electrophysiology cell model shared object. A Linux webserver is also in development.
    • Created a “batch” mode of Continuity accessible from the command line with the –batch [script] option.
    • Fixed problems with loading pickle files which make use of imaging module
    • Optimized serial and parallel biomechanics solver (for windows and linux) using a c extension for a small part of the global stiffness matrix assembly.
    • Fixed problems with using value exceptions in active and material forms if > 3 fiber angles are defined in the nodes form.

  • December 21st, 2006: Initial tests of parallel Biomechanics module results in ten-fold speed-up using MPI on 25 nodes of a Rocks Linux cluster

  • November 11th-17th, 2006: Fred Lionetti demos Continuity in the NBCR booth at Supercomputing 2006 in Tampa, FL.

  • October 31st, 2006: Continuity 6.3 revision 2486 was released.

  • October 4th, 2006: Continuity 6.3 revision 2414 was released. Highlights include:

    • The results of “List elements” can be saved
    • Biomechanics bug fixes
    • EquationsEditor can produce working Fortran code to dynamically create an ionic model

    • See release notes (deprecated) for details.

  • September 22th, 2006: Continuity 6.3 revision 2382 was released. Highlights include:

    • Critical bug fix for MacOS X
    • Fixed Windows installer
    • Detects and reports incorrect version of python (i.e. NOT 2.3) during startup.
    • Fixed fields averaging bug for rendering fields
    • Modified quads class (Element Surfaces) for greater flexibility in assigning colors. In particular, it is now possible to directly set the hsv value for any rendered surface.
