Good morning, Good afternoon,
I am testing the performance of some preconditioners on a problem I have and I wanted to try geometric multigrid. I am using a DMDA object and respective matrices (the mesh is structured, but not rectangular, it is curvilinear) I have used the default version of algebraic multigrid (that is -pc_gamg_type agg) very easily. When I try to use -pc_gamg_type geo, it returns an error. What additional lines of code do I have to add to use the geo option? Or does this require some sort of fast remeshing routine, given that I am using curvilinear grids? Thank you and have a good day. -Alfredo -- Alfredo Duarte Graduate Research Assistant The University of Texas at Austin
