Dear PETSc developers,
I have a DMPlex DM with 1 field 1dof. I'd like to output a vector with block
size equals to 3. It seems that there is no response using command line option
or using some code about PetscViewer.
The DM is generated with (note that I'm not using PetscFE for discretization,
We already merged the fix.
Thanks,
Matt

The snes options are not relevant since the parts of a PCFIELDSPLIT are
always linear problems.
By default PCFIELDSPLIT uses a KSP type of preonly on each split (that is
it applies the preconditioner exactly once inside the PCApply_FieldSplit()
hence the -fieldsplit_*_ksp_ options are n
