[petsc-users] DIVERGED_NANORINF when using HYPRE/BoomerAMG

Hi, I'm trying to solve a linear system using HYPRE/BoomerAMG as preconditioner. The system comes from a two-dimensional adjoint Navier-Stokes problem. The mesh is structured (6400 cells) and there are 24 DoFs for each cell (the matrix has a total of 153600 rows). The condition number of the

Re: [petsc-users] PETSc and Windows 10

Please use the 3.13.2 tarball, this was fixed by Satish in the previous commit I already linked (https://gitlab.com/petsc/petsc/-/commit/2cd8068296b34e127f055bb32f556e3599f17523 ). (If you want FreeFEM to do the

[petsc-users] Regarding Adding to ex11.c

Greetings, I am a master’s student in TU Delft, The Netherlands, and I am carrying out my thesis using the adaptive mesh refinement solver provided in ./ts/tutorials/ex11.c. In the process of my work, I have added a HLL Riemann Solver for the shallow water equation. I had already tested and

Greetings, Thank you for your message. Excellent! Does it suffice to ask for the merge request once I made the necessary additions to ex11.c? Regards, Mukkund > On 30 Jun 2020, at 19:16, Matthew Knepley wrote: > > On Tue, Jun 30, 2020 at 12:56 PM MUKKUND SUNJII

Re: [petsc-users] Regarding Adding to ex11.c

You want to make an MR (check to delete branch after merge and squash commits), you can mark as WIP, run the pipeline and after you get it to run clean and merge any comments, umark WIP. If it does not get merged in a few days you could ask Satish. Mark On Tue, Jun 30, 2020 at 5:12 PM MUKKUND
