[petsc-users] Missing Fortran interface for PCFieldSplitSetIS and PCFieldSplitGetIS?

[Marco Tiberga]

Dear PETSc developers,

I am developing a coupled solver for the incompressible Navier-Stokes equations, based on the PCFIELDSPLIT implemented in PETSc (I'm using version 3.10.1).
My code is written in Fortran.

I tried to follow as much as possible this example<https://www.mcs.anl.gov/petsc/petsc-current/src/snes/examples/tutorials/ex70.c.html>, but I am getting weird errors. I think the problem is in the call to PCFieldSplitSetIS.
To debug the code, for each field I wanted to call PCFieldSplitGetIS (after setting it) and print the IS with ISView. However, the compiler says the reference to PCFieldSplitGetIS is undefined.

So, I was wondering whether PCFieldSplitGetIS and PCFieldSplitSetIS are actually available for Fortran.
I tried to had a look at petsc-3.10.1/src/ksp/f90-mod/ftn-auto-interfaces/petscpc.h90, but I cannot find the interfaces for these functions.

Thanks for the clarification.
