[vtkusers] Duplication of mesh data.

[luisc]

Hello.

I'm writing a FEM program and I want to use vtk for pre and post
processing. It seems, that the standard method to do this with vtk is
that the solver writes the FEM solution to a file with vtk format and
then display this data with an vtk application.

I want to do both processes (solution and display) within the same
program, but then, if I use an vtkUnstructuredGrid container and fill it
with node/cell data from FE mesh I'll get the data stored two times in
memory (once in FE mesh and other in the vtkUnstructuredGrid). Isn't
it?.

Is there a procedure to avoid this data duplication?. I've searched the
Internet and this mailing list without success.

As you can read, English is not my native language. Sorry.

Regards.
