Greetings,
I would like to use Oges solver to solve a PDE in a simple cubic domain with
more than one refinement levels.
One option seems to be to start with a composite grid with one component
grid for the whole domain and then
add refinement grids to this base grid. Can Oges solver and
CompositeGridOperators handle this case?
I mean does the Oges solver take care of the interpolation of the unknowns
between the refined region boundaries?
Also, when generating the coefficient matrix for the solver in the usual
way, is the final coefficient matrix for the composite grid
going to include the operator coefficients for the unknowns that are hidden
by refinements?
Alternatively, should I use one component grid for each region of different
refinement and then produce an
overlapping grid, and then apply Oges?
Thanks,
George
