In general, it's best to give up on ideas like "tri-diagonal matrices" when
using a general, multi-dimensional, mesh-adaptive finite-element code. The
set of problems that could actually generate tri-diagonal matrices is
incredibly small.
Don't worry about the matrix and just use a good solver li
Thanks! I don't necessarily want to place each partition on a processor.
The idea is to renumber the DOF indices such that the matrix looks like a
block tri-diagonal matrix. I am limited to first order Lagrange elements
and probably a trapezoidal integration rule.
If I call renumber_nodes_and_elem
Renumbering and Partitioning are two different things.
You can partition along an axis using:

Hi,
Is it possible to partition a 3D mesh along x axis using the ParMetis
wrapper in LibMesh? I want to renumber the nodes and elements such that the
numbering is ordered from minimum x to maximum x.
Thanks!
