Hi, I’d like to avoid using LU, but in some cases to use ILU and still converge, I have to go to ILU(15), i.e., `-pc_factor_levels 15`. Does it still make sense, or should I give it up and switch to LU?
For this particular case, ~2k DoF, and both ILU(15) and LU perform similarly in terms of wall time. -Ling
