Re: [petsc-users] Using nonzero -pc_hypre_boomeramg_restriction_type in field split

Good to know. I may take a shot at it depending on need and time! Opened https://gitlab.com/petsc/petsc/-/issues/1362 for doing so Alex On Sun, Apr 16, 2023 at 9:27 PM Pierre Jolivet wrote: > > On 17 Apr 2023, at 1:10 AM, Alexander Lindsay > wrote: > > Are there any plans to get the missing

Are there any plans to get the missing hook into PETSc for AIR? Just curious if there’s an issue I can subscribe to or anything. (Independently I’m excited to test HPDDM out tomorrow) > On Apr 13, 2023, at 10:29 PM, Pierre Jolivet wrote: > >  >> On 14 Apr 2023, at 7:02 AM, Alexander Lindsay

Pierre, This is very helpful information. Thank you. Yes I would appreciate those command line options if you’re willing to share! > On Apr 13, 2023, at 9:54 PM, Pierre Jolivet wrote: > >  > >>> On 13 Apr 2023, at 10:33 PM, Alexander Lindsay >>> wrote: >>> >>> Hi, I'm trying to solve

OpenMP is definitely linked in and appears in the stacktrace but I haven’t asked for any threads (to my knowledge).On Apr 13, 2023, at 7:03 PM, Mark Adams wrote:Are you using OpenMP? ("OMP").If so try without it.On Thu, Apr 13, 2023 at 5:07 PM Alexander Lindsay

It would be useful to see the convergences inside the linear solve so perhaps start with -ksp_monitor_true_residual -fieldsplit_u_ksp_type richardson(this is to allow the monitor below to work) -fieldsplit_u_ksp_max_its 1 -fieldsplit_u_ksp_monitor Perhaps others,
