I was checking partitioning capabilities of Metis (mpmetis) when I noticed, that it leaves two single nodes. I have marked them in red enter image description here

Have you seen something similar or maybe it is my mistake?

The entire mesh enter image description here

Elements are typical, 8-nodal quadrilaterals. I used mpmetis without any options to create 2 partitions. It produces two partitions, where the first part contains single nodes - not connected to any elements while the second partition is fine.

Partition 1: enter image description here

Partition 2: enter image description here

Metis does not guarantee that the partitions are non-empty, so your code must deal with this situation.

  • $\begingroup$ OK, but even if the code deals with it, the loadbalancing will still be horrible, no? Why does Metis produce this output? $\endgroup$ Sep 30, 2012 at 19:50
