How do I tell metis to partition the mesh so that the partition boundaries are along x= constant lines?<br></div></blockquote><div><br></div><div>I would just use your own code for partitioning. To subvert METIS, you could prescribe large weights for edges in directions that you don't want to be cut.</div>
