Dear Mark,
Thanks for your reply. I see this mismatch. In fact my global DoF is
324. It seems like I always get the local size = global Dof / np^2, np
is my processor number. By the way, I used DMDASNESsetFunctionLocal() to
set my form function. Is it eligible to mix
It looks like your input vector is the global vector, size 162, and
the local matrix size is 81.
