The most significant improvements in this release are:

  • Important bug fixes and improvements for the multilevel Poisson solver can reduce the overall computational cost by a factor of five or more depending on the problem.
  • Variable mesh resolution along solid boundaries is now allowed and has been well tested (note however that time-adaptive variable resolution is not allowed on solid boundaries yet).
  • The robustness of the solution procedure has been much improved in the case of very complex solid boundaries.

Other improvements include:

  • Debian package snapshots.
  • Adaptive refinement of VOF-advected tracers.
  • Solid boundaries can be refined according to the local curvature.
  • Implicit Coriolis terms work with the Navier-Stokes solver.
  • Support for "thin" 3D domains.

Bug fixes:

  • Several bug fixes for special cases of solid boundaries.
  • Bug fixes for "GfsAdapt" events.
