[petsc-users] how to get the vertices belongs to a control volume in 2D?

[李季]

Hi developers:

    I have such a question that I want to get the vertices of a cell. I know I 
can get the points by


    1. Getting the faces of a cell such as "DMPlexGetCone(dm, c, &faces";


    2. Getting the vertices of every face of the cell such as 
"DMPlexGetCone(dm, f, &vertices)".

    Then I can obtain the vertices belongs to a cell. Is there any concise 
routine which I can choose to get the


vertices of a cell directly?

    Thanks
