[petsc-users] Fwd: how to set the matrix with the new cell ordering with metis

[Peng Ding]

Dear sir:
     I generate the 3D mesh with Tetgen for FVM computation.  I reordered
the cells and partitioned them with metis.  Then i got an array which
records the distribution of each cells.  For example, on CPU -0., I have:
      1, 3, 6 , 7 ....11, 22......
    But all these cells have non-continuos index, how to set the matrix in
petsc.
Regards
