[CIG-LONG] Gale 1.4.1

[Walter Landry]

Greetings,

I am pleased to announce the release of Gale 1.4.1, an implicit finite
element code for the long term tectonics community.  A new power law
creep rheology has been added, and a few bugs fixed.  You should not
have to change any input files that worked with the 1.4.0 release.
Everyone is encouraged to update.

You can download binaries or the source code from

   http://geodynamics.org/cig/software/packages/long/gale/

I have also attached a copy of the new cover picture.  Installation
instructions are in the bundled README and INSTALL files.

Cheers,

1.4.1
----------------------------------

* A bug that only shows up in 3D parallel runs with a free surface has
  been fixed.

* A bug in how stress boundary conditions are computed with
  hydrostatic terms has been fixed.

* The TemperatureProfile Standard condition function now allows
  variations of the temperature in the x-direction.

* NonNewtonian, a power law creep rheology, has been cleaned up,
  tested, and documented.

The current goals are:

  * Merge Gale back with the VPAC code.  This should give Gale multigrid
    solvers, restart capability, and improved PETSc compatibility.
  * Deformed lower boundaries
  * Interface with custom surface process models in parallel
  * User-specified non-uniform mesh spacing.
