Hi all,
Overture v26 has now been released to the Overture web page.
A partial list of changes is given below. Let me know if you have any
trouble.
#6
==============================================================================================
Overture.v26 - released August 1, 2015
Changes:
o *NOTE* You may need to rebuild your overlapping grids and or show
files with this new version.
o *NOTE* Overture now requires the Lapack and Blas libraries (previously
only CG required these)
o *NOTE* For Apple Mac's running Mavericks there are new install
instructions since gcc is nolonger
supported. You will also need to use the latest version of
A++/P++ (AP-0.8.2.tar.gz)
o New ogen grid scripts:
- loftedShipHullGrid.cmd : grid for a Wigley ship hull.
o 2012/11/24 - fixed a bug in the Neumann BC with TZ when calling with
multiple components. (neumann.C)
o 2013/08/03 - fixed bugs in ogen and the HyperbolicMapping when
building grids on a periodic channel.
o 2013/09/09 - cgcns, cgins and cgsm now have their own versions of
userDefinedInitialConditions.C and
userDefinedKnownSolution.C found the cns/src, ins/src and
sm/src, respectively)
(instead of using the version found in common/src).
o 2013/09/11 - For the explicit hole cutters in Ogen: one can now
specify which grids the explicit hole cutter
can cut holes in.
o 2013/09/27 - The CG solvers (Cgins, Cgcns, Cgsm, Cgmx, Cgasf) now
check for grid with negative volumes
and abort if any negative volumes are found.
o 2013/11/22 - fixed the cgins AFS solver so that restarts can be made
from a show file that has solutions
at a different grid resolution.
o 2013/11/30 - fixed a bug in Ogmg for singular problems with
fourth-order accuracy - these did not converge
well, if at all.
o 2014/05/18 - added option for setting variable coefficient mixed
boundary conditions with applyBoundaryConditions
such as a0(x,y,z)*u + a1(x,y,z)*u.n = g(x). See the
example in tbc.C and tbcc.C
o 2014/05/30 - changes were made so that Overture can be built on the
Mac OS X 10.9 (Mavericks) which has new compilers.
o 2014/05/31 - changes were made so that PETSc can be called from the
Mac. The main program should now call INIT_PETSC_SOLVER();
o 2014/06/02 - dues to changes for the Mac one now needs to always link
to the multigrid library libOgmg in Overture/lib
o 2014/06/02 - fixed a bug with some of the OGPolyFunction
(twilight-zone) functions that fill in array values. Some
time derivatives where not computed properly.
o 2014/06/24 - Fixed a bug in the block Tridiagonal solver -- the
transpose of the blocks were being used.
o 2014/06/24 - There is a new cg/unitTests directory that has test
routines for some of the stand-alone classes such
as the BeamModel class.
o 2014/08/06 - an initial version of a parallel tridiagonal solver has
been added to the TridiagonalSolver class,
for tridiagonal and block tridiagonal systems (not yet
for penta-diagonal). This version is
not particularly scalable.
o 2014/08/17 - The DataPointMapping now has an option to be evaluated
underneath with a NurbsMapping - this
allows higher order accurate representations of the
mapping.
o 2014/12/31 - bug fixed with hyperbolic grid generator - "match to
mapping" boundary condition was broken
when mapping was a side of an existing grid.
o 2015/03/27 - the userDefinedBoundaryValue routines have been changed a
bit. There are now separate versions for
each of the CG solvers -- Cgins, Cgcns, Cgad, etc.
o 2015/05/19 - Cgmx: added user defined known solution; fixed external
forcing with modified equation
time-stepping to be fourth-order accurate.
o 2015/05 - Cgmx is now compiled by default when typing "make" in the
main cg directory.
o 2015/05 - Cg solvers now always link to the Ogmg multigrid solver
(no need to set useOgmg := on).
