Re: [petsc-users] hypre-ILU vs hypre Euclid

It looks like Victor is working on hypre-ILU so it is active. PETSc used to have PILUT support, but it was so buggy/leaky that we removed the interface. Alexander Lindsay writes: > Haha no I am not sure. There are a few other preconditioning options I will > explore before knocking on this doo

Haha no I am not sure. There are a few other preconditioning options I will explore before knocking on this door some more. On Jun 22, 2023, at 6:49 PM, Matthew Knepley wrote:On Thu, Jun 22, 2023 at 8:37 PM Alexander Lindsay wrote:I know that PETSc has hooks for Euclid

[petsc-users] hypre-ILU vs hypre Euclid

I know that PETSc has hooks for Euclid but I discovered today that it does not support 64 bit indices, which many MOOSE applications need. This would probably be more appropriate for a hypre support forum (does anyone know if such a forum exists other than opening GitHub issues?), but does anyone h

Thank you Barry. I will try this. Should I provide a test in src/binding/petsc4py/test/test_snes.py ? Le jeu. 22 juin 2023 à 20:41, Barry Smith a écrit : > > You are not missing anything. The petsc4py stub for > SNESNASMSetSubdomains() has not been written. You could add it by adding to > > sr

Re: [petsc-users] snes_type aspin without DA example

You are not missing anything. The petsc4py stub for SNESNASMSetSubdomains() has not been written. You could add it by adding to src/petsc4py/PETSc/SNES.pyx and src/petsc4py/PETSc/petscsnes.pxi and then make a merge request https://petsc.org/release/developers/contributing/ to get it into PET

[petsc-users] snes_type aspin without DA example

Dear PETSc team, I would like to play with aspin-type nonlinear solvers. I have found several tests like snes/tutorials/ex19.c but they all use DA, which I don't want to use since I need to stick at the algebraic level. Then, I started looking at petsc4py/demo/ode/heat.py and tried to set up thing

Re: [petsc-users] petsc configure problem

Thanks for your help! Using 'mpiicc, mpiicpc, mpiifort' works well! And yes, intel compiler is used intentionally for my installation. Jiahong CHEN -- Original -- From:
