[petsc-users] A question about ghost cells

[leejearl]

Hi, everyone:

     I have a distributed DMPlex representing a 2D finite volume mesh. I 
distributed it using the function "DMPlexDistribute()".

Then, I constructed the ghost cells using "DMPlexConstructGhostCells()".

    The question is that I want to determine which cell is ghosted. I 
obtained all the cells using "DMPlexGetHeightStratum()", and

how can I kown which cell is ghosted?

    Thanks, all the helps are appreciated.
