OK that's clear know, I was askin
GAMG is primarily an algebraic multigrid preconditioner.
The geometric part is somewhat weaker and isn't the primary purpose of
GAMG,
so I would recommend using -pc_gamg_type agg for plain aggregation.
For good performance with elasticity it is important to use smoothed
aggregation,
for example,

It certainly works, however in my very limited experiecne, it's slightly
more tricky to use than Hypr
Dear all,
I was wondering if anyone has any experience using gamg with libMesh (I'm
particularly interested in elasticity)?
My main question would be if the geometric part of gamg would work with the
underlying mesh structure in libMesh?
I would appreciate any comments/recommendations,
Ata
