[overture] Re: Version 23 released

Hi Yongshen,

  If you have made changes to v22 files then you will need
to make the same changes to the v23 files. You can use the
"merge" command in Linux, for example, to automatically
add your changes to the v23 file. You will need the original
v22 file, your changed file and the v23 file.

Regards,
  Bill

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.
