Hi @fw407, When you say ILU(0) converges, do you mean you set ilu_type = 0 in your code snippet or did you just do the solve with the same ILU...

Hi @fw407, So did you try ilu_type = 0 as the preconditioner for GMRES? Did that also fail? Also, how large is the problem and how many processors are you...

Hi @fw407, If you are using just 1 processor, then the ilu_type options should not matter, and they will all be doing the same thing, which is why you see...

Hi Feng, It is actually strange to me that ILU(0) would work as a stand-alone solver for the approximate Jacobian and fail when used as a preconditioner for GMRES, especially...

Hi @fw407, That's good that no errors were found. Can you confirm that the output (update to the solution) for the 301st iteration was different for both the ILU run...

Hi @ljchan1, You should be able to access Euclid as a preconditioner for GMRES or FlexGMRES when you use precon_id 5. Hopefully this helps. -Daniel
