Yes, that's what query_elem(i) is f
Hi Derek,
Iterating over elements is NOT what I want to do. I want to operate on the i-th
element,
supposing that I know the index i. I cannot use Mesh.elem(i) because it is
unknown which
processor owns the element i.
My current solution is to iterate over all the local elements on each proce
What are you actually trying to do?
I figured you were iterating over elements and then needing to know if the
element you are currently on is owned by the local processor or not...

Hi Derek,
Thanks for your quick response. What if the elem pointer is not available,
i.e., how can I
obtain the i-th element in a parallel mesh without iterating over the mesh?
Shall I use
mesh.query_elem()?
Cheers,
Dafang
