08/01/2003: Release 0.2.0

This new release of Gerris includes a number of new features as well
as some major code restructuring. 

The GTS library version 0.7.1 is required. It includes major
improvements for boolean operations between surfaces which greatly
improve the robustness of the treatment of solid boundaries within
Gerris.

The major changes are listed below. For a detailed summary see the
ChangeLog.

New features:

- Module for OpenDX allowing direct import of Gerris simulation files.

- Support for user-defined source terms for any variable. Gaussian
  tracer source terms and constant source terms (e.g. acceleration of
  gravity in momentum equation) are provided.

- Base domain does not have to be cubic anymore. Independent length
  scales can be provided for each dimension.

- Module for OpenDX allowing direct import of Gerris simulation files.

- Updated documentation and tutorial: section about user-defined
  extension modules for initial conditions.

- Support for dynamic allocation of additional cell variables
  i.e. extension modules can dynamically add additional variables if
  needed.

- Preliminary implementation of a second-order Volume Of Fluid (VOF)
  advection scheme.

- A new GfsAdaptNotBox class can be used to specify parts of the
  domain which do not need to be refined. This is particularly useful
  for implementing absorbing outflow conditions.

Improvements and restructuring:

- Improved adaptive refinement algorithm.

- Restructuring of the test suite.

19/06/2002: Release 0.1.0

Hi all,

I am glad to announce the first "official" release of Gerris.

It needs the latest version of GTS (0.6.0) to compile.

A major change since last month is the addition of "dynamic adaptive
mesh refinement" i.e. the distribution of cells changes according to
what is happening to the solution. Have a look at the gallery on the
web site for a graphical illustration.

and here (at the bottom of the page):

I also wrote a short tutorial which should help you get started with
the code (available online and in the distribution in doc/tutorial).

Any feedback is of course welcome,

Enjoy,

Stephane
