[petsc-users] Parsing user-defined variables using YAML

[Blaise A Bourdin]

Have a look at the options related functions in the system section of the man pages: https://www.mcs.anl.gov/petsc/petsc-current/docs/manualpages/Sys/index.html
You can get options from the petsc option database and pass them to your user code.
You can also use petscBag to pass a C struct or a fortran derived type to your user code.

Regards,
Blaise

To my knowledge, the existing YAML parser in PETSc solely reads the PETSc options like snes, ksp, pc etc. as described here (https://lists.mcs.anl.gov/mailman/htdig/petsc-users/2020-August/042074.html) but is incapable to read user-defined variables, which may be specific to a code.
