I am having trouble updating my petsc command line arguments to conform to changeset 15295 that introduced shifttype.
My old settings were turn off positive definite, turn on nonzero, so I am trying to migrate from sub_pc_factor_shift_positive_definite = 0 sub_pc_factor_shift_nonzero = to sub_pc_factor_shift_type = nonzero but nonzero or NONZERO doesn't work. I can't figure out the appropriate string (assuming there is one like matrix type). Brad
