Hi, Folks -- I'm using some KSP solvers in a preconditioner (using FGMRES as the "outer" Krylov solver). For these preconditioner KSPs, I generally want to use relatively loose relative convergence tolerances.
Presently, I check to see if, e.g., -solver1_ksp_rtol, -solver2_ksp_atol, -solver3_max_it, etc., are set in the options database. If a particular value is not set in the options database, I manually set that value to some value which is different from the default PETSc value. Of course, when I use the `-help' flag, the help for each of the solvers indicates the default values for rtol, atol, max_it, etc. are the standard PETSc defaults. Is there a simple way to change these default values for individual solvers? In particular, I would like to be able to ensure that the default values listed by `-help' correspond to the values that I'm specifying in the code. Thanks, -- Boyce
