Dear PETSc team,<br><br>I would like to use the ML preconditioner from a fortran source.<br>I would like to know if there is another way to set the coarsening scheme in other way than :<br><br> call PetscOptionsSetValue('-pc_ml_CoarsenScheme','Uncoupled',ierr)<br>
call KSPSetFromOptions(ksp,ierr)<br><br>Thanks in advance,<br>Nicolas<br><br>
