Animath Changelog

New in version 1.11

April 16th, 2009
  • Lapack dependecy removed through native jacobi algorithm implementation.
  • Boundary markers can now be added (and read) for meshes that are created by passing a surfacemodel_c to the meshgenerator.
  • Cubic interpolation added
  • generation of stiffness matrices for UP formulation of nonlinear elasticity is now possible. (untested!)
  • Fixed doc for recovery_n, compound_n
  • corin split matrix available again.
  • sign of second order edge nodes have flipped.
  • SUPG solver is integrated into Animath (with possibilty for non-zero pressure boundaries).
  • Characteristc-Galerkin solver is integrated.
  • Fixed treatment of shearing components in geometric stiffness matrix generator.
  • Fixed a critical bug in mixed formulation stress recovery.
  • Made destructors virtual in classes about which the compiler complained.
  • Fixed embarrasing typo: neo-Hookian -> neo-Hookean

New in version 1.10 (January 23rd, 2009)

  • SUPG weighting for upwind stabilization is now supported, and a corresponding solver can be found among the example applications.
  • Another great methodolical enhancement is the addition of matrix generators for non-linear (including geometric non-linearity) structural analysis.
  • Matrix and load vector generation have been totally redesigned for this release, the equation_c class and its descendants have been replaced with one class for each type of matrix/load.
  • Many bugs have also been addressed, such as installation to global directories and outdated or incomplete documentation.

New in version 1.8 (November 20th, 2008)

  • Much time went into the development of mesh manipulation code, i.e. edge collapse and vertex clustering routines (see the surfacemodel_c interface).
  • Parallel solving of vector-valued problems that have decoupled components is now made easy by means of threads and employed in a new fluid solver.
  • Some quite significant enhancements can also be found in the visualization code.

New in version 1.7 (September 12th, 2008)

  • Most significantly, this version adds traction and stress recovery routines and second order surfaces with curvilinear coordinates.
  • The writing of FSI-problem solvers is (again) conveniently possible.
