Ggi linear solvers
I am using ggi in parallel and experiencing instabilities at the interception of the ggi and processor boundaries (see picture). In Jasak's presentation (http://www.openfoamworkshop.org/2009...sak_slides.pdf), 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?
