u know where I can look for the equivalent PETSc commands? Thank you.
Kind regards,

Hello,
I am trying to use the Hypre AMS preconditioner for the first time.
I am following the example problem from Hypre
https://urldefense.us/v3/__https://github.com/hypre-space/hypre/blob/3caa81955eb8d1b4e35d9b450e27cf6d07b50f6e/src/examples/ex15.c*L954__;Iw!!G_uCfscf7eWS!biuCOXkV-qD-e8iTXiwaD9
