flowris is on a distinguished road
Dear forum,

I am using ggi in parallel and experiencing instabilities at the interception of the ggi and processor boundaries (see picture). In Jasak's presentation (, he warns us to take care is in the choice of linear equation solvers.

Can anybody give me some explanation or tips on which solvers to use and which to avoid?
