GAMG = geometric algebraic multigrid?
 

Hello,
I am looking for some information on the GAMG method. I know about geometric multigrid and algebraic multigrid methods. But if GAMG is short for "geometric agglomeration algebraic multigrid" I wonder how the geometric and algebraic coarsening are combined.

Thanks
Patricia

Hello Patricia

Yes. GAMG means Geometric Agglomerated Algebraic Multigrid. You'll probably find what you need at this pdf document:
