[petsc-users] Creating a 2d geometry by using vector

[Alan Wei]

Dear All,
    I'm trying to 'draw' a 2-D cylinder in PETSc. It simply restore the x
and y coordinate values in two arrays. I wonder if I can use Vec in PETSc to
implement it (i.e. defining a vec circle) so that I can call its x or y
coordinate by circle.x or circle.y. Is this possible? also, is this a better
way than just defining it as two arrays, i.e. x[ ] and y[ ].

thanks in advance,
Alan
