Bill,
Thanks for the updates. I have a couple of questions:
1: You said (userDefinedMotion.C) the object params has been renamed
to parameters. I made some changes in the userDefinedMotion.C, can I
still use the modified subroutine in the new version?
2: Will cgmp consider the viscosity change with the temperature? I
made the change in cgins before.
Thanks,
Yongsheng

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.
