[aspect-devel] Handing nodes problem

[Lev Karatun]

Hi all,

Lately, several of my simulations crashed with a non-convergence error, and
in almost every case there was a velocity anomaly somewhere on the boundary
between different refinement levels (see attached screenshot). If I turn
off AMR, the problem goes away. I'm using an Iterated Stokes solver, the
tolerance is currently 1e-6. I tried lowering the CFL number to 0.1, but it
didn't help. I was wondering if anyone had similar problems in the past,
and what would be the common approach to deal with them?

Thanks in advance!

Best regards,
Lev Karatun.
