[aspect-devel] Handing nodes problem

[cedric thieulot]

Could you please show the viscosity (in log scale), the density and the temperature fields ?
What kind of boundary conditions are you using ?

Cedric.

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?
