It’s there already. $ ./ex1 -pc_type hypre -help|grep multipass -pc_hypre_boomeramg_interp_type: <now classical : formerly classical> Interpolation type (choose one of) classical direct multipass multipass-wts ext+i ext+i-cc standard standard-wts block block-wtd FF FF1 ext ad-wts ext-mm ext+i-mm ext+e-mm (None) Thanks, Pierre > Thanks, > Sean McIntyre
