[petsc-users] Writing VTK output for vectors derived from DM Global vector

[Garnet Vaz]

Hi,

I would like to write out my solution to a VTK file where I use unstructured
grids in DMPlex.

The solution corresponds to  harmonic frequencies (~ 5-10 distinct) which
are
currently saved into a Vec* object. These vectors were created by
duplicating the
global vector for the DM object. (I know that they correspond to the right
cell.)

Is it possible to have one file which would contain the mesh from the DM
object and all the Vec* objects?
Would I have to clone the original DM and use
http://www.mcs.anl.gov/petsc/petsc-current/docs/manualpages/Viewer/PetscViewerVTKAddField.html
to include all the vectors?

In the above function does
PetscViewerVTKWriteFunction
just need to be

myWriteFunc(vec,viewer)
{
VecView(vec,viewer)
}
if I do not need to make any changes to the vector?

Thanks.

Garnet
