Hi Matt,
I am using two PETSc DM, one for vertices (nodes), and one for cells
(elements).
I want to do the following operation:
x is a global vector generated from DM vertices, with length Nn. y is a
global vector generated from DM cells, with length Ne. I want to generate a
sparse matrix A wi

Hi all,
Good day!
I am currently working on interploating the nodal field vector I obtained
to its corresponding elemental field vector. I am doing it in a simple way
by using structured mesh, the element value is just the average of its
corresponding nodal values.
Is it possible to generate a c
