[petsc-users] List of points with dof>0 in a PetscSection

[Blaise Bourdin]

Hi,

Given a PetscSection, is there an easy way to get a list of point at which the number of dof is >0?
For instance, when projecting over a FE space, I’d rather do a loop over such points than do a loop over all points in a DM, get the number of dof, and test if it is >0.

Regards,
Blaise
