[petsc-users] PCBDDC - PCBDDCSetPrimalVerticesLocalIS

[De Groof, Vincent Frans Maria]

Hi,


I want to add a few primal vertices to the bddc preconditioner. But when checking the coarse space (using pc_bddc_check_level 1), nothing changes. Is there some special sequence that needs to be followed to add vertices?



thanks,
Vincent
