DMDAVTKWriteAll#

Write a file containing all the fields that have been provided to the viewer

Synopsis#

PetscErrorCode DMDAVTKWriteAll(PetscObject odm, PetscViewer viewer)

Collective

Input Parameters#

odm - DMDA specifying the grid layout, passed as a PetscObject
viewer - viewer of type PETSCVIEWERVTK

Notes#

This function is a callback used by the VTK viewer to actually write the file. The reason for this odd model is that the VTK file format does not provide any way to write one field at a time. Instead, metadata for the entire file needs to be available up-front before you can start writing the file.

If any fields have been named (see e.g. DMDASetFieldName()), then individual scalar fields are written. Otherwise, a single multi-dof (vector) field is written.
