v0.3

WARNING: this is a major re-factorization of the code that is not backward compatible.

Added

  • PetIBM is now a library.
  • Add include folder with all header files.
  • Add applications folder with code applications that use the PetIBM library.
  • Add some unit-tests.
  • Add instructions on how to contribute (CONTRIBUTING.md).
  • Add multi-body example (2 vertically aligned cylinders at Re=100).
  • Add moving-body example (oscillating cylinder at Re=100).
  • Require PETSc-3.8.

Changed

  • Code is now under the BSD 3-clause license.
  • Move from a single PetIBM executable to a PetIBM library with a set of application codes (Navier-Stokes solver, immersed-boundary method solvers, and post-processing utilities to compute the vorticity field and generate XMDF files).
  • Update user's documentation and API documentation. (Markdown files for user's documentation are now in doc/markdowns; API documentation is generated with Doxygen into doc/hmtl.)
  • External dependencies such as yaml-cpp, Boost, Gtest, and AmgXWrapper are now optional; they can be installed separately or when configuring PetIBM.
  • Application codes solve the systems for the velocity components, not anymore for the velocity fluxes.
  • Update previous examples with new configuration file.
  • Update Travis CI build to cache PETSc-3.8.2.

Fixed

Removed

  • Remove all Python scripts from the scripts folder. (It contained old Python scripts that were not used anymore.)
  • Cannot output the fields into PETSc binary format; only HDF5 is supported.
  • Remove Wiki pages. (User's documentation and API documentation now available here.)

v0.2

Added

  • Compatibility with PETSc-3.7 (last tested 3.7.4; cannot use 3.5 and 3.6 anymore).
  • A change log.
  • Possibility to output the numerical solution in HDF5 format.
  • Possibility to output the flux and/or velocity variables.
  • Python script createXMFFile.py that generates a .xmf file to let VisIt know how to read the HDF5 files.
  • AmgXWrapper as an optional external package (version v1.0-beta).
  • Examples to solve the 2D flow around a circular cylinder using AmgX.
  • Possibility to have multiple immersed boundaries.
  • Decoupled IBPM solver (as published in Li et al., 2016)

Changed

  • Comply Python pre- and post-processing scripts to PEP8.
  • Move validation_data files to scripts/python/verification/data and scripts/python/validation/data.
  • GAMG parameters for the 2D lid-driven cavity flow to make it run.
  • Update external package AmgXWrapper to version 1.0-beta2.

Fixed

  • Update boundary ghost points only once per time step, at the beginning of the time step.
  • Bug-fix in the methods generateBNQ() of the class TairaColoniusSolver and generateET of the class LiEtAlSolver: calculate the correct widths of the computational domain (fixed index).

Removed

  • Python script restartFromSolution.py (not finished and not necessary).
  • Non-zero initial guess as default for KSPs; the user should add -ksp_initial_guess_nonzero true to the command-line (or configuration file) to switch on a nonzero initial for a specific KSP.
