Dear petsc-users,</p>
<p style="font-family:Calibri,Helvetica,sans-serif,serif,EmojiFont;font-size:16px">
I'm solving a 2x2 block system, for which I can construct the Schur complement analytically (through compatible FEM stuff),</p>
<p style="font-family:Calibri,Helvetica,sans-serif,serif,EmojiFont;font-size:16px">
which I can pass as the preconditioning matrix.</p>

<br>
</p>
<p style="font-family:Calibri,Helvetica,sans-serif,serif,EmojiFont;font-size:16px">
When using gmres on the outer iteration, and preonly+lu on the inner iterations with a Schur complement preconditioner,</p>
<p style="font-family:Calibri,Helvetica,sans-serif,serif,EmojiFont;font-size:16px">
I see convergence in 1 iteration as expected. However, when I set gmres+lu on the inner iteration for S, I see several iterations.</p>
<p style="font-family:Calibri,Helvetica,sans-serif,serif,EmojiFont;font-size:16px">
<br>
</p>
<p style="font-family:Calibri,Helvetica,sans-serif,serif,EmojiFont;font-size:16px">
This seems strange to me, as the first result seems to confirm that I have an exact Schur complement, but the second result</p>
<p style="font-family:Calibri,Helvetica,sans-serif,serif,EmojiFont;font-size:16px">
implies not.</p>
<p style="font-family:Calibri,Helvetica,sans-serif,serif,EmojiFont;font-size:16px">
