Request: Kindly create examples with Mesh::part_dual and Mesh::part_nodal methods

[aerosayan]

Hi,

I'm really excited to use metis-rs for my CFD code.

I think it would be amazing if a few small examples were given with the library for the part_dual and part_nodal methods, since they're the most used methods in metis, and users having access to some simple test cases will help them use the library correctly.

I will try to see if I can create the examples on my own. And if I'm successful, I will submit them for metis-rs.

Thanks!

Here are a few examples using Fortran interface to metis that give a small example mesh, and partition it:

That's a very good idea. Not sure when we will have time to do this but we will try to provide it.

@cedricchevalier19 thanks!

The examples are actually conceptually simple.

We just have two arrays, eptr for element pointers, and eind for element indices.

All anyone has to do, is send them to metis as arguments to either part_dual or part_nodal methods.

    ! 0---1---4---6
    ! | 0 | 1 | 2 |
    ! 3---2---5---7

    eptr = [0,4,8,12]
    eind = [0,1,2,3,1,4,5,2,4,6,7,5]
