Dear Overture users:

Announcing the release of Overture.v23 and cg.v23.
This version should compile with the newer versions
of gcc (I use 4.3.2).

A list of some of the major changes to Overture and cg are
given below (from the Overture/CHANGES and cg/Changes files).

Please let me know if you have troubles building or using
the new version or if I have forgotten to fix some bug that
has been previously reported.


Regards,
  #6.

Overture.v23 - released  March 13, 2009

Changes:

   o NOTE: Comments in command files can now begin with # or *

   o The new version of A++/P++ supports arrays that can have 2^63 = 9e18 
elements, the previous version was
     limited to 2^31 = 2e9 elements.

   o ** Data base files now contain the Overture version number they were 
created with. If you are unable
     to read an old file with a newer version of Overture, Overture will tell 
you which older version to use.
   o fixed bug in plotting sequences in the show file.
   o fixed a bug in Oges -- the initial guess for iterative solvers was not 
being assigned properly
     for the case of systems of equations.
   o there is a new example in Overture/primer/gridPrint.C that reads a grid 
from a data base and
     outputs the grid information to a plain text file.
   o commands generated by perl in command files can now contain a comment line 
(starting with a '*' or '#')
   o the 2d contour plotter now has an option for flat-shading (toggle button) 
where the colour of each
     grid cell is constant (based on the average values at the 4 vertices)
   o fixed a bug in ogen that caused the hole-cutting to fail in some special 
cases in 2D
     (cutHolesNew.bC, line 2241)
   o fixed the hyperbolic grid generator so that it handles start curves that are 
"derivative" periodic
   o fixed a bug in Oges.C for predefined equations with mixed-BC's in which 
sometimes the system was
     wrongly thought to be singular.
   o fixed a bug in ReductionMapping.C -- the inverseMap was not correct.
   o fixed a bug in the mixed/aDotGradu/generalized-mixed BC on curvilinear 
grids -- a matrix was built
     and saved to hold the BC but this matrix was not updated if the 
coefficents of the mixed BC changed.
   o the option was added to the grid plotter to colour grids by domain number 
(for multi-domain grids)
   o there is a coefficient matrix example in tests/tcmge.C, that shows how to 
fill in arbitrary equations.
   o there is a new displayCoeff function to display elements in a coefficient 
matrix in a nice way.
   o the new version of Ogen can be used to generate grids in parallel for many 
cases (some hard cases
     that require backup interpolation will not work yet).

cg.v23 -- released March 13, 2009

Changes:


   o userDefinedMotion.C : the object params has been renamed to parameters.
   o userDefinedBoundaryValues.C : the getBoundaryData(..) functions are now in 
parameters.getBoundaryData(...)
   o There is now an option to save solution values over time at specified points using 
"probes". This information
     is written to a text file that can be plotted with the matlab script 
plotProbes.m
   o There have been many changes to cgmp. There now many examples of conjugate 
heat transfer problems that
     couple fluid flows and heat transfer.
   o The solid mechanics solver cgsm is starting to acquire some capabilities.
