Hi,
Sorry for bringing again this subject but I still have problems and this is
driving me nuts. With the serial version of cg ins I don't have problems
linking it with petsc, but with the parallel version I still have the same
problem that is:
initialize the solution...
interpolateAndApplyBoundaryConditions (start) steps=-1 t=0: number of array
ID's has increased to 684
Cgins::project: project the initial conditions <<<<
$$$$$$$$$$$$$$$ Cgins: updateToMatchGrid(CompositeGrid & cg) $$$$$$$$$$$$
Oges::buildEquationSolvers:ERROR: solver PETScNew is not currently available
You may have to copy and edit the file Overture/Oges/buildEquationSolvers.C
and a file like PETScEquationSolver.C (if you are trying to use PETSc)
and then link the files to your application in order to get a non-standard
solver
See the Oges documentation for further details
error

traceback from a debugger

mpirun noticed that job rank 0 with PID 31775 on node linux-p8i7 exited on signal 6 (Aborted).
1 additional process aborted (not shown)
the compilation process goes fine, all the necessary files are present and also
all the required libraries. I also checked the shared library dependencies
and the executable is proper linked to the petsc libraries. At this point I
dont know what could be the problem, do I need to change something in the
source code in order to have the parallel petsc solver ????
Regards,
joel

It looks like you are trying to use the serial "PETSc" solver
instead of the
parallel version. Use the "PETScNew" option when specifying the solver
to use
or "choose best iterative solver" should also work.
pressure solver options
* PETScNew
choose best iterative solver
You could also run with gdb and set a break in OgesParameters::set(
OptionEnum option, int value, real rvalue )
to make sure that the solver is set to PETScNew at some point.
Many cmd files in ins/cmd run in parallel -- grep for "mpirun" in *.cmd
for exmaples

Hi,
The PETSc option is switch on in the makefile. Also the
buildEquationSolvers.o and PETScSolver.o are proper linked. The compilation
process goes fine but when I try to use parallel ins I always get the same
error. Besides the file cicp.cmd, is there another parallel example??
cheers,
jg
