I see. I will try if I can find something. For now, the slowdown happens in
the FGMRES solver by the way. Thanks!

I don't see why hanging nodes would make any kind of difference for this
combination (in fact, for any equation). If I were you, I'd

I'm solving for a SUPG stabilized slightly compressible Navier-Stokes
equation, with a Schur complement type preconditioner.

Hi Wolfgang,
I realized something after I posted my question, so I removed it after a
while. Sorry that my original post is not shown in the thread. After
checking the output block IDs in ParaView I found that it was not
the unbalanced load that caused the slow computation, but somehow the

Hi All,

Hello,
I'm merging two geometries in dealii. If the cells of both geometries don't
match up, will that give hanging nodes, or will the code not be able to
handle this?
Kind regards,
David
